摘要： An apparatus for reducing energy consumption in monitoring means of a plurality of piezoelectric components comprises a plurality of piezoelectric components as well as monitoring means for monitoring the status of the piezoelectric components. The monitoring means have two states namely active and inactive. The piezoelectric components are connected in parallel to each other. A current detecting circuit comprises a switch and a resistor that is connected in parallel to the switch. A controller having two states that are active and inactive. The controller is configured to open the switch in response to the controller being in the inactive state and to close the switch in response to the controller being in the active state. The closing of the switch triggers a state change in the monitoring means from their inactive state to their active state.
