In this disclosure, a description of a system for providing feedback signals relating to input signals provided to an electronic device is provided. The system comprises: an input device; a transducer associated with the input device; and a feedback module to generate a feedback signal indicating activation of the input device on the electronic device based on signals from the input device. The input device may be a touchpad; the transducer may be a piezoelectric element; and the feedback module may cause the transducer to vibrate upon receiving an activation signal relating to activation of the input device. The feedback module may provide a voltage generated by the transducer during the activation of the input device to an energy storage circuit. |
