Abstract:

A method, an apparatus, and a computer program product for powering a battery-less wireless input device are provided in which the battery-less wireless input device is coupled with a short-range communications target. The short-range communications target includes an energy harvester for harvesting energy generated by a short-range communications initiator when the short-range communications initiator communicates with the short-range communications target. The battery-less wireless input device receives the harvested energy for powering itself from the energy harvester when the short-range communications initiator communicates with the short-range communications target. The battery-less wireless input device may include a capacitor for storing the received harvested energy. Accordingly, the input device may electrically operate without being powered by a battery, and may therefore have a reduced size and weight.
