"Development of Soft Rubbery and Curvy Electronics towards a Seamlessly Integration with Human"


While human organs and tissues are mostly soft and curvy; conventional electronics are hard and planar. Seamlessly merging electronics with human is of imminent importance in addressing grand societal challenges in health and joy of living. However, the main challenge lies in the huge mechanical mismatch between the current form of rigid electronics and the soft curvy nature of biology.
In this talk, I will first describe a new form of electronics, namely “rubbery electronics”, with skin-like softness and stretchability, which is constructed all based upon elastic rubbery electronic materials. As the core basis of rubbery electronics, rubbery semiconductor has been developed through composite engineering based on commercial available materials and manufactured in a scalable and reliable manner. These materials, manufacturing and device innovations set a foundation to realize fully rubbery electronics, circuits and sensors. In particular, rubbery transistors, logic gates, integrated electronics, sensors, smart skins, implants, neuro devices, and integrated function systems will be demonstrated. In the second part of the talk, I will introduce the invention and development of conformal additive stamp (CAS) printing, a novel, reliable and versatile manufacturing technology for developing 3D curvy electronics. Electronics with 3D curvilinear layouts, especially in the size range from millimeter to centimeter with accuracy of microns, are technically very challenge to build. The major hurdle lies in the lack of a proper manufacturing technology. Therefore, CAS printing has been developed to solve this long-standing manufacturing challenge. Systematic understanding and validations, and extensive employment of CAS printing for various curvy electronics will be presented to illustrate its manufacturing fidelity. Devices such as smart contact lens with integrated sensors and electronics for multiple diagnostic functions will be demonstrated. Soft and curvy electronics have opened a new paradigm for personal healthcare, medical diagnosis, biological studies, human-machine interfaces, soft machines, etc.
