Title:
SELF-POWERED SENSOR DEVICE AND SELF-POWERED SENSOR SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/050112
Kind Code:
A1
Abstract:
A self-powered sensor device and a self-powered sensor system using the same are disclosed. A self-powered sensor device according to one embodiment can comprise a sensor unit, a communication unit for transmitting data reflecting a sensing value of the sensor unit, and a heat generating module comprising: a thermoelectric module comprising a pair of main surfaces having a high temperature surface thermally connected to a high temperature object and a low temperature surface, which is the surface opposite to the high temperature surface, a plurality of thermoelectric materials disposed between the pair of main surfaces and generating electric power by using a temperature difference, caused by the high temperature object, between the two main surfaces, and a support member filled between the two main surfaces so as to support the thermoelectric materials; and a heat dissipating member connected to the low temperature surface.
