Abstract
The present disclosure discloses a method and apparatus for identifying discharge failure of a piezoelectric circuitry. The apparatus comprises a piezoelectric circuitry consisting of charging and discharging circuit with a microcontroller to compute the time required to charge and discharge the piezoelectric element respectively. Based on the first charging time and the second charging time corresponding to the first and second charging-discharging cycle respectively, the difference between the first and the second charging time is determined. The discharge failure in the piezoelectric circuit is identified where the first charging time is greater than the second charging time.
