SYSTEMS AND METHODS FOR BATTERY-LESS WIRELESSLY POWERED DIELECTRIC SENSORS

Document Type and Number:

WIPO Patent Application WO/2020/106440

Kind Code:

A8

Abstract:

Wirelessly powered dielectric sensor in accordance with embodiments of the invention are disclosed. In many embodiments, a wirelessly powered dielectric sensor includes an RF-power receiving antenna that receives electromagnetic power, a power management unit (PMU) including a capacitor to rectify and store the electromagnetic power, and a dielectric constant sensing sensor, where the PMU monitors harvested energy and operates the dielectric sensing sensor; and where the dielectric sensing sensor senses a dielectric constant of a material that is in close proximity.
