HYBRID RESONANT STRUCTURE FOR VERIFYING PARAMETERS OF A TYRE

摘要

In order to enhance road safety, the control of running conditions, and in particular of the physical parameters of a tyre are recommended. The invention concerns a sensor for determining various factors such as the temperature or the pressure of tyres. The sensor is a passive hybrid resonant structure which can be integrated on the ground contact of the vehicle, in particular in the gum of the tyre during manufacture. The passive hybrid resonant structure can comprise a volume wave and piezoelectric film resonator.
