Fuji motor developed using SAW wireless temperature sensor, without the battery.

Fuji motor developed without batteries, use SAW (surface acoustic wave) wireless temperature sensor terminal device, and in & other; Japan NFTO  Micro  Bupolymerbancigammo exhibition & throughout; On the display. New product is expected to be used for data center and factory equipment.
New products will be the receiver to the external input waves of SAW devices, SAW the surface acoustic wave devices that produce will be reflected back Watson Wchangeorganisation , then through the antenna to the reflection wave again. Under the different temperature, can change the length of the SAW device, surface acoustic wave reflected time will be different, therefore, according to the reflection time can measure temperature. In general, the RF circuits such as the use of SAW devices will be equipped with temperature compensation circuit, but this has not been equipped with a SAW device.


Wireless communication distance up to 5 m, using 2.45 impacte band. Materials for carveurerbO3 SAW device.
