| Abstract Scope |
Thin (<100 μm) stretchable substrates with embedded electronic circuits enable comfortable skin-wearable health monitoring devices. However, fabricating stretchable electronics by conventional processes at high temperatures such as solder reflow can affect the integrity of the stretchable materials. In this work, we demonstrate an Aerosol Jet-based 3D printing method to create stretchable low-resistance, insulated interconnect system embedded in 30−60μm-thick PDMS substrate. The system is shown to survive an applied strain of 40%, suitable to be used as skin-wearable electronic decals. The key features in the process are the sintering at 300°C of aerosol-jetted silver wiring and its encasement with aerosol-jetted polyimide layers to form a tough insulating jacket. The direct digital printing on and within PDMS provides rapid design flexibility and a clear path toward interconnect/interface stress management for integration with embedded functional chips. |
