An apparatus, a method, and a computer program product are provided. The apparatus may be a mobile device. The mobile device receives a first mechanical force applied to at least one region on the mobile device, performs a function unrelated to energy conversion in response to the first mechanical force, receives a second mechanical force applied to the at least one region on the mobile device, converts the second mechanical force into electrical energy using at least one piezoelectric element, and powers at least one component of the mobile device using the electrical energy. |
