Abstract
A deformation detection sensor including: a piezoelectric element which generates an output signal due to a deformation; a reference signal input device which inputs a reference signal of a predetermined cycle to the piezoelectric element; a first signal extraction device which extracts a first output signal due to the deformation of the piezoelectric element out of an output signal from the piezoelectric element; a second signal extraction device which extracts a second output signal due to the reference signal out of the output signal from the piezoelectric element; a first evaluation device which evaluates the first output signal extracted by the first signal extraction device; and a second evaluation device which evaluates the second output signal extracted by the second signal extraction device.
