Capacitive sensor technology detects movements while seated

Avoiding discomfort with the help of capacitive sensors


Conducted on behalf of Daimler AG, the objective of the driving simulator study is to validate the “Mobilization Seat” developed by Daimler Research.

Benefits of the Mobilization Seat

  • Maintains the health and motivation of long-distance truck drivers
  • Counteracts the lack of exercise
  • Reduces sick days and stoppages.

The study is being conducted with 16 working long-distance truck drivers under realistic conditions in a driving simulator at the Fraunhofer IIS premises.
The simulator consists of a Mobilization Seat that encourages subjects not to sit still. The capacitive motion sensor technology integrated into the seat detects and analyzes movement behavior.


Lack of exercise becomes a habit

What long-distance truck drivers and office workers have in common is that they spend long periods seated and suffer from a lack of movement in the workplace. And the consequences for each individual? Back pain and a stiff neck due to the one-sided load on the spine and muscles. Prolonging this habit can lead to poor posture and muscle tension.

What is a proactive way to ensure changes in sitting position, even under heavy workload and stress, and prevent complaints?

One answer is provided by Daimler AG’s Mobilization Seat, which features integrated Fraunhofer IIS capacitive sensor technology.

Capacitive sensor technology for improved health in the workplace

Fraunhofer IIS capacitive sensor technology is being used to investigate changes in posture while seated.

How the Mobilization Seat works

  • Air cushions in the backrest/seat surface are activated (dynamic stimuli)
  • Program sequences developed with medical/physiotherapy/sports science experts
  • Counteracts the effects of excessive sitting
  • Maintains vigilance during monotonous / partially automated driving (already proven in driving study using EEG measurements)

Added value of capacitive sensor technology

  • Effortless integration into any seat and backrest textiles
  • Low sensor height of less than 1 mm, no influence on seating comfort
  • Breathable, no influence on the seat climate
  • Highly sensitive
  • Real-time transmission of data via Bluetooth
