Built-in steering wheel sensors ward-off driver's hand slip

June 23, 2015 // By Julien Happich
In cooperation with Guttersberg Consulting, Krippner Inc. has developed a foil-based sensing technology that can measure pressure in addition to position. In one implementation scenario, the SensoFoil could be used to measure the driver’s hand position and pressure on a car’s steering wheel.

During normal driving, a driver is constantly moving his/her hands on the steering wheel, changing pressure as the fingers grip the wheel. By sensing how the driver’s hands are moving, the SensoFoil could detect if the driver has fallen asleep with their hands on the wheel or even if their hands had slipped off the steering wheel. This detection could trigger the correct safety protocol to either wake up the driver or to implement corrective measures, such as the vehicle taking full control to a safe stop along the road.

In case of a medical emergency, the car could even drive itself to the closest medical emergency centre while sending out an alert to the appropriate authorities.

The sensor can also be programmed for pressure in certain locations. This can be used in a vehicle to control various location, emergency, entertainment or communication systems. This same feature can be used in game controllers, aircraft, etc., as an economical way to add additional programmable capabilities to a controller or joystick device without the need for extra buttons or dials.
