TDK lifted sales of its Sensor Application Products 18.6% to JPY 224.6 billion in its year to March 2026, with Hall and tunnel magnetoresistance (TMR) sensors growing in sales and profit, its [fiscal 2025 results](https://www.tdk.com/system/files/20264q_0mqf56xw_en.pdf) show, while TE Connectivity's sensors sales were flat in its year to September 2026, its [results of 28 October 2026](https://www.sec.gov/Archives/edgar/data/0001385157/000110465926119326/tel-ex99d1.htm) state. The thin film sensors technology market covers sensors whose sensing element is a film a few nanometres to a few micrometres thick, sputtered or evaporated onto a substrate: magnetoresistive, pressure and strain, platinum temperature, piezoelectric MEMS, gas and humidity, and thermopile infrared sensors, valued at the price the sensor maker realises. Douglas Insights sizes it at USD 8.62 billion in 2025, about 6.2 billion sensors at an average USD 1.39, and at USD 14.45 billion in 2035, a 5.30% compound annual growth rate (CAGR). The study sits in our [sensors and instrumentation coverage](https://www.douglasinsights.com/industry/sensors-instrumentation/), beside the [Temperature Sensor Market](https://www.douglasinsights.com/temperature-sensor-market/), [Automotive Radar Market](https://www.douglasinsights.com/automotive-radar-market/) and [Actuators Market](https://www.douglasinsights.com/actuators-market/) reports; every figure follows the Douglas Insights [research methodology](https://www.douglasinsights.com/research-methodology/).

## Which thin film sensor type leads: magnetoresistive, pressure or temperature?

Thin-film magnetoresistive sensors lead with 30.0% of 2025 value, about USD 2.59 billion, Douglas Insights estimates. Piezoelectric thin-film MEMS sensors grow fastest, 7.0% a year to USD 2.03 billion by 2035.

| Sensor type | Share 2025 | Value 2025 | CAGR 2026-2035 | Value 2035 |
| --- | --- | --- | --- | --- |
| Magnetoresistive (AMR, GMR, TMR) sensors | 30.0% | USD 2.59 billion | 6.4% | USD 4.81 billion |
| Thin-film pressure and strain sensors | 24.0% | USD 2.07 billion | 4.2% | USD 3.12 billion |
| Thin-film platinum and NTC temperature sensors | 18.0% | USD 1.55 billion | 4.0% | USD 2.30 billion |
| Piezoelectric thin-film MEMS sensors (AlN, ScAlN, PZT) | 12.0% | USD 1.03 billion | 7.0% | USD 2.03 billion |
| Thin-film gas and humidity sensors | 10.0% | USD 862 million | 5.2% | USD 1.43 billion |
| Thermopile infrared and other thin-film sensors | 6.0% | USD 517 million | 3.6% | USD 736 million |

Magnetoresistive sensors lead because every electric motor, steering column, wheel-speed point and smartphone compass needs a position or current reading, and TMR stacks deliver it at a fraction of the power of a Hall element. Murata began mass production of two anisotropic magnetoresistive (AMR) sensors drawing 20 nA and 80 nA on average in a 1.0 x 1.0 x 0.4 mm package for capsule endoscopes, earbuds and smart locks, its [release of 13 April 2026](https://www.businesswire.com/news/home/20260413296947/en/Murata-Launches-Ultra-Low-Power-AMR-Sensors-to-Boost-Battery-Life-in-Healthcare-and-Wearables-Devices) states. The segment grows 6.4% a year in our model.

Thin-film pressure and strain sensors, USD 2.07 billion, sputter a resistor bridge straight onto a steel diaphragm and are used in brake, transmission, hydraulic and refrigerant lines; they grow 4.2% a year as cars move to brake-by-wire and heat pumps. Thin-film platinum temperature sensors, USD 1.55 billion, grow 4.0%: Yageo Nexensos, formerly Heraeus Nexensos, showed a platinum thin-film sensor that is sintered onto silicon carbide power modules, rated above 200 °C and as small as 0.5 x 0.3 mm, at SENSOR+TEST, [messe.tv reported on 26 May 2025](https://www.messe.tv/en/2025/sensor-test/yageo-nexensos-platinum-thin-film-sensor-for-power-modules). Piezoelectric MEMS sensors, USD 1.03 billion, grow fastest from ultrasonic fingerprint, microphone and gesture uses. Gas and humidity sensors, USD 862 million, grow 5.2%; Sensirion, a Swiss maker of thin-film humidity and gas sensors, grew 2025 revenue 23.8% to CHF 342.4 million, its [results of 10 March 2026](https://sensirion.com/media/media/file/49AD8396/69AEF646/Sensirion_2025_Full_Year_Results_Media_Release_EN.pdf) show. Thermopile and other sensors, USD 517 million, grow 3.6%. Segment values for 2035 sum to USD 14.43 billion, 0.17% below the headline.

## What drives thin film sensor demand: electric vehicles, robots or smart devices?

Thin film sensor volume rises 6.8% a year in our base case, from about 6.2 billion units in 2025 to about 12.0 billion in 2035. Four drivers add 8.40 points of gross growth; restraints remove 1.60 points.

### Electrified vehicles and battery safety: 3.20 points

Vehicle electrification is the largest driver, worth 3.20 points. Carmakers built 96.4 million vehicles in 2025, up 3.9%, and China built 16.63 million new energy vehicles, up 29%, the International Organization of Motor Vehicle Manufacturers (OICA) reported on [23 April 2026](https://oica.net/auto-industry-growth-shifted-east-in-2025-amid-global-repositioning/). An electric car carries current, rotor-position and battery temperature sensors that a petrol car does not; Douglas Insights estimates an electric car uses 25 to 35 thin-film sensing elements against 12 to 18 in a combustion car. China's battery safety standard GB 38031-2025, effective 1 July 2026, requires that packs must not catch fire or explode, [SMM reported on 30 June 2026](https://news.metal.com/newscontent/103980319-dua-standar-nasional-kendaraan-listrik-wajib-mulai-berlaku-besok-baterai-tidak-boleh-terbakar-atau-meledak), which adds temperature and pressure sensing per module.

### Industrial robots and factory automation: 2.00 points

Automation adds 2.00 points. Factories installed 603,307 industrial robots in 2025, up 11%, the operating stock passed 5.08 million and installations are forecast at 655,000 in 2026, the International Federation of Robotics (IFR) [World Robotics 2026 summary of 24 September 2026](https://ifr.org/img/worldrobotics/Executive_Summary_WR_2026_-_Industrial_Robots.pdf) shows; China took 354,000, 59% of the total, the [IFR China release](https://ifr.org/downloads/press_docs/EN-2026-SEP-24-IFR_Press_Release_WR-CHINA.pdf) adds. Each robot joint carries magnetic encoders and torque sensors, often thin-film strain gauges, and Douglas Insights estimates a six-axis robot uses 20 to 30 thin-film sensors. Honeywell reported double-digit growth in sensing within its USD 1.12 billion Industrial Automation segment in the third quarter of 2026, its [results of 22 October 2026](https://www.sec.gov/Archives/edgar/data/0000773840/000077384026000141/exhibit99-q32026earningsre.htm) state.

### Consumer devices and wearables: 1.80 points

Consumer electronics add 1.80 points. Ultra-low-power AMR and TMR sensors, piezoelectric MEMS microphones and thin-film humidity sensors go into earbuds, watches, smart glasses and locks. TDK's magnetic sensor growth came from information and communication technology as well as automotive markets in its year to March 2026, its [results](https://www.tdk.com/system/files/20264q_0mqf56xw_en.pdf) show. Douglas Insights estimates a premium smartphone uses 6 to 10 thin-film sensing elements and a true wireless earbud pair 4 to 6.

### Power electronics and AI data centres: 1.40 points

Power electronics add the last 1.40 points. Silicon carbide modules in inverters, chargers and server power supplies need fast temperature and current sensing, which is why Yageo Nexensos aimed its sintered platinum thin-film sensor at power modules, per [messe.tv](https://www.messe.tv/en/2025/sensor-test/yageo-nexensos-platinum-thin-film-sensor-for-power-modules). Infineon booked record quarterly revenue of EUR 4.17 billion in the quarter to June 2026 on AI power demand and completed its purchase of ams OSRAM's non-optical sensor portfolio, worth about EUR 230 million a year, on 1 July 2026, its [release of 5 August 2026](https://live.deutsche-boerse.com/news/EQS-News-Infineon-Technolgies-AG-Q3-FY-2026-concluded-with-record-sales-driven-by-strong-AI-business-further-significant-increase-in-revenue-and-margin-expected-in-Q4-FY-2026-5fd33ab1-1e11-4cd8-a8a6-8e06fb98cb0e) states. Summed, 3.20 + 2.00 + 1.80 + 1.40 = 8.40 points, a Douglas Insights estimate.

## What restrains thin film sensors: weak car demand, inventory or silicon substitutes?

Two restraints remove 1.60 points a year from thin film sensor volume: customer inventory cycles take 0.90 points, and substitution by integrated silicon Hall and MEMS sensors takes 0.70 points.

Inventory cycles hit hard in 2025. Sensata's revenue fell 5.8% to USD 3.70 billion in 2025, its [full-year results](https://www.sensata.com/contact/newsroom/sensata-technologies-reports-fourth-quarter-and-full-year-2025-financial-results) show, Melexis's sales fell 10% to EUR 839.6 million, its [results of 4 February 2026](https://www.melexis.com/en/news/2026/financial/melexis-q4-2025-results) state, and TE Connectivity's sensors sales fell 7.6% in its year to September 2025, its [results of 29 October 2025](https://www.sec.gov/Archives/edgar/data/1385157/000110465925103388/tel-20251029xex99d1.htm) show. Douglas Insights estimates automotive and industrial buyers ran down about two months of sensor stock in 2025, and the recovery is uneven: TE's sensors were still flat organically in fiscal 2026.

Substitution takes 0.70 points. Hall-effect sensors built inside a standard CMOS chip cost less than a separate magnetoresistive film in many angle and current uses, and Allegro MicroSystems, a Hall-led supplier, grew fiscal 2026 sales 23% to USD 890.1 million, its [release of 7 May 2026](https://investors.allegromicro.com/news-releases/news-release-details/allegro-microsystems-reports-fourth-quarter-and-fiscal-year-2026) shows. The World Semiconductor Trade Statistics (WSTS) organisation left its sensors forecast unchanged in its [August 2026 update](https://www.wsts.org/76/Global-Semiconductor-Market-records-exceptional-growth-in-Q2-2026), the only segment not raised. Douglas Insights estimates that about 15% of the angle and current sensing sockets now served by thin-film magnetoresistive parts could move to integrated Hall chips by 2035, mostly in cost-sensitive body and seat electronics, while TMR keeps the high-accuracy steering, motor and battery current positions where its signal-to-noise advantage and low power matter most.

## Which region uses the most thin film sensors, and where is growth fastest?

Asia Pacific uses the most thin film sensors, USD 4.48 billion or 52.0% of 2025 value, because vehicles, phones and robots are assembled there. It also grows fastest, 5.9% a year to USD 7.95 billion by 2035.

| Region | Value 2025 | Share 2025 | Value 2026 | CAGR 2026-2035 | Value 2035 |
| --- | --- | --- | --- | --- | --- |
| Asia Pacific | USD 4.48 billion | 52.0% | USD 4.75 billion | 5.9% | USD 7.95 billion |
| Europe | USD 1.81 billion | 21.0% | USD 1.89 billion | 4.4% | USD 2.78 billion |
| North America | USD 1.72 billion | 20.0% | USD 1.81 billion | 4.9% | USD 2.78 billion |
| Latin America | USD 259 million | 3.0% | USD 271 million | 5.0% | USD 421 million |
| Middle East and Africa | USD 345 million | 4.0% | USD 364 million | 5.6% | USD 594 million |

Asia Pacific leads on assembly. China built 34.53 million vehicles in 2025, more than a third of the world total, [OICA](https://oica.net/auto-industry-growth-shifted-east-in-2025-amid-global-repositioning/) data show, and installed 59% of the world's new industrial robots, the [IFR](https://ifr.org/downloads/press_docs/EN-2026-SEP-24-IFR_Press_Release_WR-CHINA.pdf) reports. Japan is home to TDK, Murata and Alps Alpine, and South Korea and Taiwan supply phone and chip makers. Europe, USD 1.81 billion, grows 4.4%: its Euro 7 rules apply to new light-duty vehicle types from 29 November 2026 and to all new light-duty vehicles from 29 November 2027, a [UK Department for Transport memorandum of 2 September 2026](https://assets.publishing.service.gov.uk/media/6a9aea4af5b35599aec1925b/20260904_-_EM_ON_TWO_EU_ACTS_APPLICABLE_IN_NORTHERN_IRELANDsigned.docx.pdf) notes, and German and Swiss makers such as Yageo Nexensos, Sensirion and WIKA are based there.

North America, USD 1.72 billion, grows 4.9% on aerospace, medical, industrial and data-centre demand, where Honeywell and TE Connectivity are strongest. Latin America, USD 259 million, grows 5.0% from Mexican vehicle plants, and the Middle East and Africa, USD 345 million, grow 5.6% from oil, gas and water metering, Douglas Insights estimates. Regional values sum to USD 9.08 billion in 2026 and USD 14.53 billion in 2035, 0.55% above the headline.

## Which companies dominate thin film sensors?

TDK, TE Connectivity, Sensata, Yageo Nexensos, Murata, Honeywell, Infineon and Sensirion hold about 45% of thin film sensor value, Douglas Insights estimates; TDK, with its TMR and thin-film temperature lines, is the largest at about 9%.

| Company | Thin film sensor lines | Latest reported figure | Source date |
| --- | --- | --- | --- |
| TDK | TMR, Hall, temperature, pressure, piezo MEMS | FY to March 2026 sensor products JPY 224.6 billion, up 18.6% | FY2025 results |
| TE Connectivity | Thin-film pressure, strain, temperature | FY2026 net sales USD 19.89 billion; sensors flat | 28 October 2026 |
| Sensata Technologies | Pressure, temperature, position | Q3 2026 revenue USD 1.00 billion, up 7.7% | October 2026 |
| Sensirion | Humidity, gas, flow | 2025 revenue CHF 342.4 million, up 23.8% | 10 March 2026 |
| Melexis | Magnetic and temperature ICs | 2025 sales EUR 839.6 million, down 10% | 4 February 2026 |
| Murata | AMR sensors | Ultra-low-power AMR in mass production | 13 April 2026 |
| Yageo Nexensos | Platinum thin-film temperature | No separate figures disclosed | Douglas Insights estimate |

TDK sets the pace in magnetoresistive sensing. Its sensor products grew from JPY 189.5 billion to JPY 224.6 billion in a year while group sales rose 13.6% to JPY 2,504.8 billion, its [fiscal results](https://www.tdk.com/system/files/20264q_0mqf56xw_en.pdf) show, and Douglas Insights estimates about half of its sensor revenue is thin-film based. TE Connectivity, the connector and sensor maker, grew fiscal 2026 net sales 15.2% to USD 19.89 billion, but its sensors line, which includes sputtered thin-film pressure sensors, slipped 2.4% organically, its [28 October 2026 results](https://www.sec.gov/Archives/edgar/data/0001385157/000110465926119326/tel-ex99d1.htm) show.

Sensata, a pressure and temperature specialist, returned to growth with third-quarter 2026 revenue up 7.7% to USD 1.00 billion, including a USD 24.0 million customer termination payment, and guided fourth-quarter revenue of USD 942 million to USD 972 million, its [results](https://www.sec.gov/Archives/edgar/data/0001477294/000147729426000050/q326pressrelease.htm) show. Infineon strengthened its sensor range by buying the ams OSRAM portfolio, and Honeywell's sensing grew at a double-digit rate. Sensirion is the fastest-growing listed specialist, with 2026 guidance of 5% to 12% growth in constant currency to CHF 335 million to CHF 360 million, its [10 March 2026 release](https://sensirion.com/media/media/file/49AD8396/69AEF646/Sensirion_2025_Full_Year_Results_Media_Release_EN.pdf) states.

## How much does a thin film sensor cost, from a TMR die to a pressure transducer?

A thin film sensor realises an average USD 1.39 in 2025, Douglas Insights estimates, from under USD 0.30 for a high-volume TMR or AMR die to USD 4 to USD 6 for a packaged platinum element and more than USD 20 for a thin-film pressure transducer.

Distributor prices show the ladder. Vishay's PTS1206 thin-film platinum surface-mount sensor, built to the IEC 60751 standard for a -55 °C to +175 °C range, listed from USD 4.80 each on LCSC, its [product page](https://www.lcsc.com/product-detail/C320418.html) showed on 6 November 2026; reel prices for carmakers run well below that, a Douglas Insights estimate. Murata's AMR parts fit a 1.0 mm square package, its [April 2026 release](https://www.businesswire.com/news/home/20260413296947/en/Murata-Launches-Ultra-Low-Power-AMR-Sensors-to-Boost-Battery-Life-in-Healthcare-and-Wearables-Devices) notes, the size class where unit prices fall to tens of cents in phone volumes.

Average price falls 1.4% a year in our base case, to about USD 1.21 in 2035. Wafer-level thin-film processing, larger 200 mm sensor fabs and Chinese competition push like-for-like prices down 3% to 4% a year, while a richer mix of TMR and piezoelectric MEMS parts claws back about 2 points, Douglas Insights estimates. Melexis's 2025 sales drop of 10% included a 2% currency effect, its [results](https://www.melexis.com/en/news/2026/financial/melexis-q4-2025-results) show, and Douglas Insights reads the rest as volume and price pressure in automotive sensing.

## What if EV demand slows or robots spread faster: what is the 2035 forecast?

The thin film sensors technology market ends 2035 between USD 11.69 billion and USD 17.49 billion across our three cases, around a base of USD 14.45 billion. Vehicle electrification and price erosion set most of the spread.

| Case | Sensor volume leg | Price leg | Revenue rate | 2035 value |
| --- | --- | --- | --- | --- |
| Slower | 5.20% | -2.00% | 3.10% | USD 11.69 billion |
| Base case | 6.80% | -1.40% | 5.30% | USD 14.45 billion |
| Faster | 8.20% | -0.80% | 7.33% | USD 17.49 billion |

In the slower case electric car growth stalls outside China, Hall-in-CMOS sensors take more angle and current uses and Chinese producers drive prices down faster, taking 1.6 points off volume and 0.6 points off price. In the faster case robot installations keep growing at the 11% rate of 2025, humanoid and service robots add joints, and power-module sensing spreads through AI data centres, adding 1.4 points of volume and 0.6 points of price. One extra point of yearly revenue growth adds about USD 1.43 billion to 2035 value, a Douglas Insights estimate.

Live signals sit close to the base case. Sensata's 6.8% organic growth in the third quarter of 2026 and TDK's 18.6% sensor growth point up, while TE's flat sensors and the unchanged [WSTS sensors forecast](https://www.wsts.org/76/Global-Semiconductor-Market-records-exceptional-growth-in-Q2-2026) of August 2026 point to a slow recovery. The signal to watch is the IFR's 2026 installation count against its 655,000 forecast.

## Which rules shape thin film sensor demand, from GB 38031 to Euro 7?

Three rule sets shape thin film sensor demand: battery safety standards for electric vehicles, vehicle emission and particle rules in Europe, and refrigerant rules for heating and cooling equipment.

China's GB 38031-2025 and GB 18384-2025 took effect on 1 July 2026, replacing the old rule that only required a warning 5 minutes before a battery fire with a requirement for no fire and no explosion, and giving already approved models until July 2027 to comply, [SMM reported](https://news.metal.com/newscontent/103980319-dua-standar-nasional-kendaraan-listrik-wajib-mulai-berlaku-besok-baterai-tidak-boleh-terbakar-atau-meledak). Douglas Insights estimates the rule adds 4 to 8 temperature and pressure sensing points per pack.

Euro 7, Regulation (EU) 2024/1257, applies to new heavy-duty vehicle types from 29 May 2028 and all heavy-duty vehicles from 29 May 2029, after the light-duty dates, and a delegated act adopted on 9 June 2026 moves its brake-particle test to UN Regulation 179, the [UK memorandum](https://assets.publishing.service.gov.uk/media/6a9aea4af5b35599aec1925b/20260904_-_EM_ON_TWO_EU_ACTS_APPLICABLE_IN_NORTHERN_IRELANDsigned.docx.pdf) states. In the US, the Environmental Protection Agency's Technology Transitions reconsideration rule pushed some refrigerant deadlines out, moving cold storage from 1 January 2026 to 1 January 2032, [Holland & Knight reported on 26 May 2026](https://www.hklaw.com/en/insights/publications/2026/05/epa-finalizes-changes-to-technology-transitions-provisions), which slows the shift to new refrigerants that need thin-film leak and pressure sensing.

## Douglas Exclusive: the Thin Film Content Ledger for thin film sensors

The Thin Film Content Ledger is a Douglas Insights model built from 14 inputs: 10 company filings or releases, 2 association datasets and 2 trade reports. It tracks how many thin-film sensing elements each end product carries.

| Date | Input | What it moves |
| --- | --- | --- |
| 26 May 2025 | Yageo Nexensos: power-module platinum sensor | Power content |
| 29 October 2025 | TE: FY2025 sensors down 7.6% | Inventory cycle |
| 4 February 2026 | Melexis: 2025 sales down 10% | Inventory cycle |
| February 2026 | Sensata: 2025 revenue down 5.8% | Inventory cycle |
| 10 March 2026 | Sensirion: 2025 revenue up 23.8% | Gas and humidity |
| 13 April 2026 | Murata: ultra-low-power AMR launch | Consumer content |
| 23 April 2026 | OICA: 96.4 million vehicles, 16.63 million Chinese NEVs | Vehicle base |
| 7 May 2026 | Allegro: FY2026 sales up 23% | Hall substitution |
| FY to March 2026 | TDK: sensor products up 18.6% | Magnetic content |
| 30 June 2026 | SMM: GB 38031-2025 in force | Battery content |
| 5 August 2026 | Infineon: ams OSRAM sensor deal closed | Supply structure |
| 24 September 2026 | IFR: 603,307 robots installed | Robot base |
| 22 October 2026 | Honeywell: double-digit sensing growth | Industrial content |
| 28 October 2026 | TE: FY2026 sensors flat | Inventory cycle |

The finding, a Douglas Insights estimate: weighted by 2025 output, the average vehicle carried about 18 thin-film sensing elements and the average new industrial robot about 25, and electrification lifts vehicle content by about 0.8 elements a year. Carried through our model, vehicles take 29% of thin-film sensor units in 2025 and 35% in 2035, while consumer devices fall from 48% to 42% as phone volumes stay flat.

The ledger changes how to read the market. Sensor makers whose revenue fell in 2025 were hit by inventory, not by falling content: the number of thin-film elements per car and per robot kept rising. Douglas Insights therefore forecasts units from end-product content rather than from supplier revenue, and expects the 2025 dip to reverse by 2027.

## How does the methodology turn 6.2 billion sensors into USD 8.62 billion?

Our methodology multiplies about 6.2 billion thin film sensors in 2025 by an average USD 1.39 each to reach USD 8.62 billion, then grows units 6.8% and lowers price 1.4% a year.

The model covers 6 sensor types and 5 regions, using 56 data points, 23 sourced and 33 modelled. Units come from an end-product build: about 1.8 billion in vehicles, 3.0 billion in consumer devices, 0.7 billion in industrial equipment and robots, 0.4 billion in heating, cooling and building systems and 0.3 billion in medical, aerospace and other uses, Douglas Insights estimates drawn from OICA vehicle output, IFR robot installations and per-product content counts. Arithmetic: 6.2 billion x USD 1.39 = USD 8.62 billion; USD 8.62 billion x (1.068 x 0.986)^10 = USD 14.45 billion. Units reach about 6.6 billion in 2026 and 12.0 billion in 2035.

Two cross-checks agree. First, TDK's JPY 224.6 billion of sensor sales, about USD 1.5 billion, of which about half is thin-film based, gives roughly 9% of our market, consistent with its leading rank. Second, TE's sensors line, about USD 0.9 billion in fiscal 2025 derived from its reported decline, carries a thin-film share that equals about 5% of our market. AI tools help draft the text and automated checks test the arithmetic and links; the Douglas Insights research desk chooses the sources, builds the model and approves publication, as our [editorial standards](https://www.douglasinsights.com/editorial-standards/) explain.

## What counts in the thin film sensors study, and what is excluded?

The thin film sensors study counts sensors whose sensing layer is deposited by sputtering, evaporation or chemical vapour deposition, sold as dies, elements or packaged sensors. Thick-film, wire-wound, bulk silicon piezoresistive and CMOS Hall sensors are excluded.

The study splits value by 6 sensor types and 5 regions: Asia Pacific, Europe, North America, Latin America, and the Middle East and Africa. Broader temperature sensing sits in our [Temperature Sensor Market](https://www.douglasinsights.com/temperature-sensor-market/) report, vehicle radar in the [Automotive Radar Market](https://www.douglasinsights.com/automotive-radar-market/) study and the motion devices that sensors control in the [Actuators Market](https://www.douglasinsights.com/actuators-market/) report.
