Manufacturing, Materials, and Device Innovations for Soft and Curvy Electronics
In this talk, I will present some of our recent research progress on manufacturing, materials, and device innovation for stretchy and curvy electronics. Existing strategies to enable mechanical stretchability in soft electronics heavily rely on special mechanical architectures, which impose a heavy burden on sophisticated fabrication and associated cost. I will show our recent results on developing a completely new set of stretchable electronics, namely "rubbery electronics, circuits and sensors". Such devices are based on all-elastomeric electronic materials and therefore intrinsically stretchable without the need of any special structural design. The stretchable rubbery electronics mimics the format and functionalities of our elastic human skin. I will then show our recent progress on developing 3D curvilinear shaped devices. A new manufacturing approach, namely conformal additive transfer printing, will be presented. Different type of 3D curvilinear device such as smart contact lenses with integrated sensors and electronics for multi-functionalities will be demonstrated.
