  • Patent number: 9885620
    Abstract: In a pressure detecting apparatus, a pressure sensor includes a piezoelectric sheet that generates a piezoelectric signal according to a load that is applied. A touch detecting unit detects contact with the pressure sensor. An acquirer acquires a piezoelectric output based on the piezoelectric signal. A rate-of-change calculator calculates a rate of change with respect to time of the piezoelectric output acquired within an arbitrary time range before a touch detection time when the touch detecting unit detects contact with the pressure sensor. An applied pressure calculator calculates applied pressure by correcting the piezoelectric output acquired after an end time of the time range used in the calculation of the rate of change using the rate of change. The apparatus enables precise measurement of applied pressure in a pressure sensor.
