Capacitive sensor technology detects movements while seated

Avoiding discomfort with the help of capacitive sensors

Objective

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.
 

Motivation

Lack of exercise becomes a habit

What long-distance truck drivers and office workers share is prolonged sitting and limited movement during their work hours. What are the consequences for individuals? Back pain and stiff necks result from the uneven strain on the spine and muscles. Continuing this behavior can lead to poor posture and increased muscle tension.

What proactive strategies can be implemented to modify sitting positions, even during high workloads and stress, to prevent discomfort?

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

Fraunhofer IIS's 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, and 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 <1 mm, no influence on seating comfort
  • Breathable, no influence on the seat climate
  • Highly sensitive
  • Real-time transmission of data via Bluetooth
