PURPOSE: Wireless detecting apparatus and method for micro-generation are provided to perform long distance measurement without external power supply. CONSTITUTION: A wireless detecting apparatus for micro-generation comprises a piezoelectric generating part(110), an electric signal generating part(130), a surface acoustic wave generating part(140), a sensed-value encoding part(150), a surface acoustic wave encoding part(160) and a sensed signal output(170). The piezoelectric generating part changes and outputs the mechanical energy to the electric energy. The electric signal generating part receives the electric energy from the piezoelectric generating part and generates a preset band of electric signals. The surface acoustic wave generating part converts the electric signal and generates surface acoustic wave. The sensed value encoding part encodes the sensed value from a sensor. |
