A wireless electronic device with a kinetic-energy-to-electrical-energy
converter is disclosed. In one embodiment, the wireless electronic device
comprises a control mechanism, a kinetic-energy-to-electrical-energy
converter, and a movable user interface element, wherein movement of the
movable user interface element provides both signal information to the
control mechanism and kinetic energy to the
kinetic-energy-to-electrical-energy converter. The
kinetic-energy-to-electrical-energy converter converts kinetic energy
provided by movement of the movable user interface element to electrical
energy and provides the electrical energy to the wireless electronic
device. In one embodiment, the wireless electronic device takes the form
of a radio frequency identification (RFID) device with multiple
identifiers and a control input.
