Tpms Sensor Batteryless

Smallest size available only 18mm diameter x 14mm.
Tpms sensor batteryless. Stack s unique batteryless tyre pressure and temperature monitoring system tpms has eliminated the electronics and batteries from the sensors providing new limits of performance for tpms and significantly increasing sensor life to 5 seasons or more. Sensors contain batteries typical life time 3 5 years after which the whole sensor must be replaced. The solution is done by an energy harvester. No programming nor activation required.
I want to design a tpms and i ve heard that the market is getting into batteryless solutions meaning the s tx sensors and transmitter and the entire circuit inside the tires won t need batteries at all as it is complicated to replace. Some tpms sensors use a 1 250 volt nickel metal hydride battery. The battery based sensors are typically 35 70g each plus the need for a counterweight. Batteryless with projected life of 20 years thanks to our patent pending rfid technology.
The battery is encased in the sensor s molded plastic housing. Stack tyre pressure and temperature monitoring systems tpms. Tire pressure monitoring sensors are usually powered by a 3 volt lithium ion battery. Sensor positions are determined automatically.
Lightest tpms sensor available only 15g which means it can be used as a partial counterweight to the valve. Sensor life time.
