Wireless Powering of Ultra-low-power Sensors

Abstract

This study evaluates the remote powering of ultra-low-power sensors with wireless power transfer technology. Magnetic resonance wireless powering was assessed with respect to longitudinal and lateral positions of sensors. The developed solution operates in the ISM band (13.56 MHz). The study showed that wireless powering of ultra-low power sensors at relatively long distances is a realistic approach leading to practical use cases.
