Abstract: A physical quantity sensor (100), which can detect multiple physical quantities simultaneously has flexibility or bendability over the entire body thereof. The sensor (100) has a first electrode layer (2) formed on a substrate (1) and first and second piezoelectric elements (3a, 3b) arranged in parallel on the electrode layer (2). Two additional electrode layers (4a, 4b) are formed on the piezoelectric elements (3a, 3b). The substrate (1), the electrode layer (2), first piezoelectric element (3a), one of the additional electrode layers (4a) and protective layers (5a, 5b, 5c, 5d, 5e) constitute a first physical quantity detection unit (6), and the substrate (1), the first electrode layer (2), the second piezoelectric element (3b) and the other additional electrode layer (4b) (a fourth electrode layer) constitute a second physical quantity detection unit (7).

Abstract: Temperature compensation is performed using a computation program for temperature compensation, a computation processing, and a sensor. Deformation in a diaphragm caused by a pressure change due to the temperature of the gas in a cavity is cancelled out, and deformation of the diaphragm is minimized within the target temperature range, thereby allowing an optimum temperature compensation to be performed. The temperature compensation in a capacitance-type sensor executes calculation steps which include including a calculation step (S17) of acquiring the amount of change ?C? in capacitance. A parameter ?C? is obtained, through which it is possible to determine the degree of compensation for the deformation in the diaphragm section caused by a pressure change due to the temperature changes of the gas in the hermetically sealed space.
