ABSTRACT:
A holster for a handheld electronic device. The holster has integrated therein one or more piezoelectric elements that provide an output voltage to the handheld electronic device upon insertion of device in the holster. The output voltage can be used to charge the battery of the device, to power, at least in part, the device, or both. The output voltage is generated by harvesting vibration energy at the piezoelectric elements upon the holster being subjected to acceleration caused by a user carrying the holster when walking, running, or during any other suitable activity.
