Tire balancing product
Automobile Tire pressure monitoring system (TMPS) is used to monitor the tire pressure automatically and it could alarm for tire leakage or low pressure. The most current TPMS product is with the battery TPMS, which needs batteries to provide power, the battery will bring some drawbacks: such as large size, heavy quality, Battery life issues, when serious temperature problems, the battery capacity will be reduced and the battery’s chemical is not environment friendly.
The power generation of piezoelectric ceramics could replace the battery, to provide the possibility for the realization of passive TPMS.
Using the constant pressure of tire rotation, the piezoelectric ceramic will generate constant pressure in the tire and will provide continuous energy for TPMS, which is based on piezoelectric effect.
