N2 - In this work, a self-powered wireless defor-mation sensor system is designed, fabricated, and char-acterized. The self-powered monitoring is realized by thecombination of the low-power operation of a sensor systemand energy harvesting from a weak stray magnetic field.The magnetic energy harvester (MEH) is a resonating elec-tromagnetic device based on a cantilever beam structure,capable of generating 113.6 μW power under a stray mag-netic field with a very low amplitude of 50 μTrms at 50 Hz. Theharvested power is used to charge a battery and then powera deformation sensor system with an average operationcurrent of 18.0 μA and voltage of 3.3 V. Finally, experimentalresults confirm that the proposed self-powered sensor sys-tem can be used to monitor the deformation of an expansionjoint on a gas-insulated switchgear (GIS).
