Systems and methods for remote sensing of air gaps using a capacitor sensor array

Abstract:

A system for remote sensing of air gaps includes a substrate and a capacitor sensor array attached to the substrate, where the capacitor sensor array includes a plurality of capacitor sensors. The system also includes a transmit antenna attached to the substrate, and a microprocessor electrically connected to the transmit antenna and the capacitor sensor array. The microprocessor is configured to switch on and off at least one capacitor sensor of the plurality of capacitor sensors and to transmit determined air gap measurements using the transmit antenna.
