Presentation Summary

Printed sensors are of high-interest on 3D and flexible substrates using a variety of metal and resistive materials. Aerosol Jet® is an ideal printing tool for precision deposition of polymeric and metal inks for these sensors. It is a non-contact, high resolution printing technology that is compatible with a wide range of conductive, insulating, and resistive materials. We present the printing of robust and flexible circuits and sensors using a variety of materials including Ag, Cu, and CuNi metal inks. Through the use of laser sintering we demonstrate low-temperature sintering on a variety of substrates. We also present the functionality of strain gauge and thermocouple printed sensors in terms of robustness with flexing, thermal coefficients, resistance stability, gauge performance, and thermocouple Seebeck coefficient. Finally, we address material optimization for Aerosol Jet® 3D printing and process optimization to mitigate resistance drift and optimize flexing stability for such sensors.
