摘要： A strain measuring system includes a piezoelectric element and a resistor provided on an object. The system also includes a resistance detection circuit to detect a change in resistance of the resistor, and a piezoelectric effect detection circuit to detect a piezoelectric effect of the piezoelectric element. A strain calculation circuit detects a strain changing time while the strain of the object is changing using a detection result from the piezoelectric effect detection circuit, calculates a change in resistance of the resistor during the strain changing time, and calculates a degree of strain of the object using a calculation result of the change in resistance.

摘要： The present disclosure relates to a method and a device for measuring a force action. The disclosure additionally relates to an input apparatus which uses such a device or such a method. In a first step, a voltage pulse resulting from a force action on a force sensor is generated by a charge amplifier. Using this voltage pulse, a trigger pulse may be generated by a comparator circuit. A voltage value derived from the voltage pulse is then stored in a storage capacitor by a current mirror. The capacitor voltage resulting therefrom may be evaluated by an evaluation unit.
