Thesis topic: Wireless Power Monitoring at Plugs and PanelsAdvisor: Kristofer S.J. PisterAffiliations: BSAC and SWARM LabMy thesis research focused in deployable, low-cost solutions for non-intrusive power measurement at plugs and circuit breakers by sensing electric and magnetic fields. I also worked on a fully-integrated, above-Vt energy source for smart dust sensor motes that includes microscale photovoltaic cells and a switched-capacitor DC-DC converter built on the same substrate in 180nm CMOS.See www.michaelclorek.com
