Flexible Electronics Fabrication Using Inkjet-printing Technology for Fully-passive Wireless Body-worn Patch Sensors
Inkjet printing (IJP) technique is a relatively new additive manufacturing process for low temperature thin film deposition of various material-based inks on planar substrates. After evaporation of the ink solvent, the substrate is left with custom designed patterns. This technology offers low temperature thin film depositions of materials in nanoparticle (NP) format that can be layered to fabricate flexible electronics on a variety of surfaces. Ability to fabricate electronic components might allow large-area low-cost fabrication of µm-thin electronic circuits on flexible materials for various applications including body-worn patch sensors. We have utilized IJP for fabrication of thin film resistors and capacitors printed with Ag, PVP, PPy, and other inks on substrates such as paper and polyimide with our patented multilayer IJP fabrication technique. In another research thrust, we have developed patent pending fully-passive body-worn wireless and battery-less sensors (WRAP sensors) on paper that will be able to collect physiological data during regular daily activities. We further seek to investigate these physiological data to provide insights into the health status of users through our custom smartphone mHealth app with real-time signal processing, feature extraction, and classification towards a smart and connected community (SCC).
