[nanoPost] Smart Sensor for tires

Research Center Germany

This institute's scientists work on smart materials with flexible properties. When the temperature or the electromagnetic field in their environment changes, these materials change shape and position, are more ductile (or more rigid) or show a modified electromagnetic vibration behavior.

Presently, research is focused e.g. on adaptive thin film materials that will be applied for example in very small sensors. In a common project with the Goodyear Company, a sensor for tires which is mounted into the tread of the pneumatic tire, is being developed.

While driving, it analyzes the road condition and detects black ice or aquaplaning as not only the tire but also the sensor itself is subject to specific deformations. In the future, the sensor shall be linked with the anti-lock braking system of the vehicle in order to shorten the braking distance and to make the vehicle safer.

"Smart" thin film materials can also act as actuators in micro pumps and micro valves. Shape memory materials make wearing orthodontic wires much more comfortable as they have to be readjusted rarely. The scientists have already registered a patent regarding a fabrication process of such materials.
