UK entrepreneurs develop PiezoTag for next-generation TPMS

ERJ staff report (DS)

Coventry, UK -- A UK start-up company claims to have developed a smart tyre sensor, which uses a piezo electric generator to power a pressure- and temperature-sensor mounted within the tyre.

The device is mounted on the inside surface of the tyre, adhering to the innerliner at a point corresponding to the crown of the tread area. In this sense, it employs a similar concept to the systems developed separately by Pirelli and Continental.

The comapny's website says, "Piezotag Limited has developed the world's first proven piezo power source for Tyre Pressure Monitoring Systems (TPMS) in response to industry led demands for a battery free product. The performance of the technology has been independently verified. "

The site continues, "Direct TPMS require a pressure and temperature sensor, a Radio Frequency transmitter and a power source, whether that be battery or the now more favoured power harvesting technology. With this technology it is possible to take accurate pressure readings from each tyre and transmit the data directly to the driver. "

it concludes, "Developed by Piezotag and tested to 250kph, the patented patch solution can be fixed to all pneumatic tyres in use today. The technology can be scaled for small (PV) and large (CV) applications. Dependent upon the intended application, adhesive cure times can be instantaneous, (contact adhesive) or have a 24 hour cure time."
