Document Type and Number:
WIPO Patent Application WO/2014/175521
Kind Code:
A1
Abstract:
An accelerometer using a piezoresistor is disclosed. The accelerometer comprises: an outer wall support having a shape of an opened portion of which the interior is vertically pierced; a mass body located in the outer wall support and enclosed by the outer wall support; four hinges for connecting the outer wall support and the mass body to each other and serving as a spring; and four piezoresistors connected between the outer wall support and the mass body. Further, when receiving a shock from the outside, the accelerometer can measure the size of the shock through a resistance change of the piezoresistors generated according to movement of the mass body.
