Abstract
A bending sensor is provided that includes a piezoelectric element disposed on a bendable substrate; a voltage detection circuit that detects a voltage generated in the piezoelectric element; and an arithmetic unit that calculates an integrated value by integrating the voltage detected by the voltage detection circuit and associates the integrated value with a bent state of the substrate. Moreover, the arithmetic unit calculates in advance a corrected integrated value obtained by correcting a maximum value of the integrated value with a decrease value resulting from a stress relieving effect, associates the corrected integrated value with a first bent state of the substrate, and normalizes a calculated integrated value based on the corrected integrated value.
