LATEST PROJECTS
Project | 01: Multi-band Ambient RF Energy Harvesting for Self-powered Sensors
Designed and implemented a multi-band, adjustable RF energy harvesting(RF-EH) circuit for harvesting from LTE 700MHZ, GSM 850MHZ, and ISM 900MHZ bands with one single circuit, which can constantly operate TI eZ430-RF2500 sensor at multiple city locations. Demonstrated efficiencies of up to 45% in LTE 700, GSM 850, and ISM 900 bands.
Project | 02: Software-Defined Distributed Energy Beamforming
Led prototype development of a wireless charging system, which uses a distributed energy beamforming algorithm implemented in software-defined radios (SDRs). This approach allows multiple SDRs that act as uncoordinated energy transmitters to self-adjust their transmission so that the net energy transfer to the target receiver is constructive.
Project | 03: Multi-tissue Heterogeneous Channel and Tissue Safety Analysis
Derived safe bounds on electric (E) and magnetic (H) fields that can be coupled to live human tissues and analyzed the worst case rise in tissue temperature for concurrent and continuous transmission under varying blood perfusion rates. Performed electromagnetic field analysis, frequency dependent channel characterization using electrical circuit model, FEM & FDTD based models, and porcine tissue testbed. Thermal & electrical tissue safety analysis, noise & interference study were also included in this study.
