ENERGY HARVESTER AND SELF POWERED WIRELESS SENSOR MODULE USING 2-WAY COMPRESSION LOAD

摘要

Disclosed are an energy harvester and a self-powered wireless sensor module using a two-way compression load. It includes a case, a piezoelectric device which is received in the case and has a first and a second surface which are supported by both insides of the case, and a vibration transmission member which is installed to move relatively in the case and pressurizes the first and the second surface of the piezoelectric device by a straight reciprocating motion according to the vibration of a vibration source, and generates two-way compression load to the piezoelectric device.
