My Car, my Health Center: The Future of Automotive Health

Imagine a future where your vehicle not only transports you safely from A to B but also actively monitors your health, including cognitive load, during every journey. This vision is rapidly becoming a reality with the integration of health technologies in the automotive sector, a concept better known as Automotive Health. As the automotive industry transforms, applied research institutions like Fraunhofer IIS are essential in essential in advancing health monitoring on the road..

Taking stock: How cars are evolving into mobile health centers

The incorporation of sensor technologies in vehicles enhances the ability to monitor health conditions effectively. (Read more on sensor integration in everyday objects in our overview article From Idea to Product.) Some of the key technologies include:

• Wearable devices track relevant metrics such as heart rate and electrodermal activity (EDA), providing a comprehensive view of the driver’s health.
  • Commercial wearables include smartwatches, smart rings, or chest straps. The challenge when using commercial systems, however, is synchronizing data and accessing the raw data.
  • maphera^® is a mobile, wireless, and extendable sensor platform that facilitates collecting and analyzing automotive health data among other application scenarios (learn more about maphera’s working principle “Plug and Research“).
  • CardioTEXTIL is a textile multi-channel ECG for continuous arrhythmia monitoring and unobtrusive in daily activities like driving.
• Camera-based systems analyze facial skin color changes to estimate heart rate, offering a non-invasive monitoring method but might face data privacy issues.
• Multi-touch sensors measure high-resolution physiological parameters like ECG and PPG through sensors integrated in steering wheel, armrests, or gear knobs.
• Textile-integrated pressure sensors in seats detect movement and assess the driver’s physical state and serve as a preventive measure against immobility especially for truck drivers (read below for more) .

Health Monitoring in the Age of Autonomous Driving

Autonomous driving features like adaptive cruise control and lane centering make driving a breeze, but it’s crucial to factors in the driver’s emotional and cognitive state for safety. Even when drivers have their hands and feet off the controls, they still need to stay alert and ready to jump back in, as distractions — such as chatting with a passenger or scrolling through playlists — can easily shift attention away from the road.

To better understand these dynamics, we rely on our unique data acquisition environments, including a driving simulator that enables the collection of multimodal data on driving behavior, driver states, well-being, and cognitive load (learn more).

This setup was the backbone of ADABase, our Autonomous Driving Cognitive Load Assessment Database. Curious to dive deeper?

Transforming driving through textile‑integrated sensors

One of the most promising Automotive Health technologies we’ve introduced – textile‑integrated sensors – now takes center stage. A standout innovation in smart materials, this technology creates touch-sensitive fabrics that can be seamlessly incorporated into vehicle interiors. Beyond interaction, these sensor-integrated textiles enable the monitoring of touch and pressure data. Seats or steering wheels equipped with embedded sensors can, for example, help assess stress levels or physical conditions, supporting a safer and more comfortable driving experience.

Capacitive sensor matrix for pressure measurement

At the core of our textile‑integrated sensing solutions is a textile-integrated sensor matrix that measures pressure distribution in real time – ultra‑thin (≈ 0.5 mm), breathable, and seamlessly embedded into automotive seating (learn more). This technology enables precise movement and posture analysis and underpins applications such as the Mobilization Seat, which was evaluated in a research study conducted in our driving simulator.

By using capacitive sensor technology to analyze movement patterns and seating positions, the Mobilization Seat takes health on the road one step further. It encourages movement to combat the downsides of long hours spent sitting, helping drivers stay comfortable and engaged while on the go.

Good for gold … standard: Validating Automotive Health solutions

Having explored the technologies that enable Automotive Health, we now shift gears – from innovation to validation. Because promising sensing technologies only become viable automotive solutions when their effectiveness is proven through well‑designed subject studies.

At Fraunhofer IIS, we validate wearable and embedded Automotive Health solutions through customized, multimodal studies that link psycho‑physiological responses directly to driving behavior and safety. Our driving simulator provides a controlled yet realistic environment, supported by a fully synchronized measurement infrastructure and AI‑based data analysis.

By fusing biosignals from wearables and integrated sensors, we enable robust assessment of driver and passenger states such as overload, fatigue, attention, and stress. All studies are tailored to customer requirements:

• Study setup: The individual requirements of the customer define the type of data collected, the test group, and the data analysis.
• Data collection: Our measurement infrastructure for biosignals, questionnaires, etc. is perfectly synchronized and quickly ready for use. 
• Modalities: HR and HRV via ECG, EDA, respiration, muscle activity with EMG, EEG, gaze direction, questionnaires, and more.
• Driving simulator: The setup provides the perfect environment for quickly testing new technologies for their suitability for use in road traffic.
• Data analysis: We use AI-based algorithms to analyze multimodal data in accordance with customer specifications.

With a well-developed network of scientific partners, Fraunhofer IIS offers transparency and flexibility, providing clients with complete datasets and insights rather than a “black box” approach.

By integrating findings from these subject studies into the development of wearable technologies, we can significantly enhance the understanding of driver health and safety, paving the way for a more responsive and proactive automotive health ecosystem.
