Smart Deposition Process Integrates Sensors and Heaters into Coatings

Abstract Direct write technology is an innovative and economical materials deposition process that integrates conductive traces, antennas, circuits, and sensors onto components or embeds them within structures. The process has been in development since 2002 for use in aerospace, military, and energy markets. This article describes its use to print thermocouple sensors, heat flux sensors, heaters, conductors, and antenna patterns.
