Printing of High-Resolution Wireless and Passive Wear Sensors (Printed Electronics USA 2019)

Dr Sameh Dardona, Associate Director, Research & Innovation
United Technologies Research Center
United States

Presentation Summary

This presentation will describe a novel design and fabrication of a wear sensor that can be additively manufactured using a variety of electronic printing methods for in-situ monitoring of wear and abrasion of materials. The sensor design incorporates a circuit with closely spaced and narrow interconnect traces connected to a set of parallel resistors. The entire design can be printed conformal to the surface or embedded into a material to detect the depth of the groove generated during abrasion of the material. The presentation will additionally include high resolution sensor designs enabled by additive manufacturing as well as implementation for wireless and passive operations of the embedded sensor.
