Abstract
An energy-autonomous elevator system control element includes a piezoelectric layer and processing unit for detecting a control operation, a transmitting unit for wirelessly transmitting at least one signal to a remote elevator system controller, the at least one signal being generated automatically by the elevator system control element on the basis of the control operation, and an energy recovery unit for supplying electrical energy for the elevator system control element. The energy-autonomous elevator system control element can be used as a car operating panel or a landing operating panel in an elevator system.
