Feasibility of a battery-less wirelessly-powered RFID remote control system

In this paper we present a study on the feasibility of a wirelessly-powered battery-less remote control system. Such system, that is based on a passive multi-RFID scheme, has been recently proposed as an eco-friendly alternative to conventional infra-red battery-assisted technology. The proposed remote control unit does not require batteries and it is remotely powered by an RFID reader which is embedded in the device to be controlled (e.g. a TV). However, some questions related to cost effectiveness, feasibility and safety have been posed. Accordingly, we discuss these issues and we propose strategies to optimize the system performance. The extent of the presented study covers also general Wireless Power Transmission Systems, especially in which concerns user safety (maximum exposure levels).
