SWITCH proposed research deals with communications and hardware aspects of Wireless Power Transfer (WPT). More specifically:

• Conceptual and physical implementation of novel SWIPT receiver topologies.
• Wireless Powered Sensor Networks theoretical analysis – Requirements for antenna array transmitters as power beacons.

  SWITCH intends to investigate new receiver topologies for Simultaneous Wireless Information and Power Transfer (SWIPT), study their feasibility and experimentally evaluate their performance in comparison with the conventional topologies. The main difference of the proposed receiver topology compared to the existing ones is the sequential decoding on the DC signal, the exact same signal that is used for energy harvesting. This approach requires the power splitting after the rectification of the received RF signal as opposed to the usual practice where the power splitting was taking place for the RF signal. As a result a different set of restrictions in the design and implementation on the rectifying circuit and the subsequent DC-to-DC booster that is followed by the dynamic power divider applies. 

 SWITCH will provide the theoretical study of the new receiver topology. For the implementation of the receivers, the constituent components of antenna, rectifier, and energy storage interface circuit will be implemented, before. All individual components will be co-designed as parts of the complete receiver, and design and optimization of the components occurs simultaneously and interchangeably.
 SWITCH also aims to theoretically study nertorks of Wireless Powered Sensors and research the requirements and feasibility of transmitters needed for WPSNs. In this approach transmitters are regarded primarily as power beacons exploiting concepts of radiation beam steering, optimized waveforms and sensors localization. Finally the developed receivers and the implemented antenna array, will be tested in a joint experimental setup.
