Conventional batteries/cords-based pow ering solutions will not sustain their extensive deployment\, considering incurred cost\, feasibility\, and most of all\, environmental impact. Ther efore\, a transformative powering solution for such large-scale and geogra phically scattered wireless devices becomes particularly important in supp orting the widespread implementation while mitigating the environmental bu rden.\n\nIn this talk\, I will introduce our research on efficiently harne ssing and recycling microwave energy to power wireless sensing and communi cations. First\, I will present a city-wide RF survey in Montreal to fully understand how much ambient RF energy is available in our environment\, a n essential reference for designing recycling circuits that can work in th e real world. Next\, I will discuss our systematic analysis and understand ing of far-field wireless power harvesting\, enabling us to identify effec tive ways to enhance harvesting efficiency. Then\, I will describe our adv ances in harmonic backscattering communication in the sub-6 GHz and millim eter-wave bands\, including architecture improvement\, accurate nonlinear analysis\, and detection range enhancement. Finally\, I will conclude this talk with my outlook on emerging opportunities for battery-free wireless sensing and communications.\n\nCo-sponsored by: IEEE Montreal\n\nSpeaker(s ): Dr. Xiaoqiang Gu\, \n\nRoom: L-2710\, Bldg: Polytechnique University\, 2500 Polytechnique Montreal Road (Quebec)\, Pavilion Lassonde \, Montreal\ , Quebec\, Canada\, H3T 1J4 LOCATION:Room: L-2710\, Bldg: Polytechnique University\, 2500 Polytechnique Montreal Road (Quebec)\, Pavilion Lassonde \, Montreal\, Quebec\, Canada\ , H3T 1J4 ORGANIZER:IEEE.SB.POLY@gmail.com SEQUENCE:12 SUMMARY:Towards Battery-Free Wireless Sensing and Communications URL;VALUE=URI:https://events.vtools.ieee.org/m/320970 X-ALT-DESC:Description: <br /><p>Our life is becoming more convenient\, eff icient\, and intelligent with the aid of fast-evolving wireless technologi es\, which require a massive deployment of interconnected but geographical ly scattered wireless sensing and communication devices.
