Direct Write Inkjet Printing of Miniature Sensors

SI2 proposes to leverage its experience in Direct Write technology to inkjet print passive and active sensors and circuitry for use in medium range munitions. Formulations of dielectric, resistive, conductive and magnetic inks will be deposited to show the feasibility of manufacturing complex electronics using a wide format, roll to roll inkjet process. Our innovative approach is based on using well-known design criteria for functional sensors, modifying the design according to SI2’s Direct Write inkjet printing capabilities and integrating the requisite inks with both the substrate and the jetting assembly. SI2 will address the three areas of design, manufacturing and materials collectively to make inkjet printed complex sensors a potential reality. In Phase I, SI2 will modify its current stable of inks to develop four functional types; dielectric, resistive, conductive and magnetic. A demonstration article, such as an LRC circuit, will be inkjet printed and characterized. A manufacturing plan will be developed to provide a foundation for future demonstrations in the Phase II. The follow-on Phase II program will refine the sensor concept and develop functional antenna and GPS sensor demonstration devices for use in medium range munitions.
