Title:
DISTORTION SENSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/208531
Kind Code:
A1
Abstract:
The distortion detecting device according to the present invention is provided with: a deforming body for distorting in response to an inputted load; a piezoresistor provided on the deforming body, the resistance value of the piezoresistor being changed in response to distortion; an input resistor having a predetermined resistance value; a non-inverted input terminal to which a first potential comprising a predetermined constant potential is connected; an inverted input terminal to which one terminal of the piezoresistor and one terminal of the input resistor are connected, and to which a second potential comprising a predetermined constant potential different from the first potential is connected via the input resistor; and an operational amplifier having an output terminal to which the other terminal of the piezoresistor is connected.
