Worcestershire Company Makes Self-Powering TPMS

Worcestershire-based Morgan Electro Ceramic, has developed technology which can power car tyre pressure monitoring systems (TPMS) using wheel movement instead of batteries. The technology, described as a piezoelectric bimorph, enables TPMS manufacturers to design self-powered remote sensors that accurately measure tyre pressure, with none of the lifetime and disposal issues associated with batteries.

Morgan Electro’s “bimorphs” are based on established that uses the movement of the wheel and pressure of the tyre as it hits the ground, transforming it into electrical energy. The bimorphs generate enough electrical energy to power a wireless signal that transmits valuable data about the pressure in the tyre to an on-car receiver.

According to a report in The Engineer, the Piezoelectric bimorphs also support the development of an intelligent TPMS, which would be capable of collecting more data about the tyre and road conditions and communicating with other systems within the vehicle.
