Abstract: Internet of things (IoT), robotics, big data and artificial intelligence (AI) hold the key to Industry 4.0, which is identified as cyber-physical systems. To stay relevant in the AI age, humans must collaborate with robots or even merge with electronics and machines to realize internet of health (IoH), augmented reality (AR), and augmented human capabilities. However, bio-tissues are soft, curvilinear and dynamic whereas conventional electronics and machines are hard, planar, and rigid. Over the past two decades, soft electronics blossom as a result of new materials, novel structural designs, and digital manufacturing processes. This talk will discuss our research on the design, fabrication, conformability, and functionality of soft bio-integrated and bio-mimetic electronics based on inorganic functional materials such as metals, silicon, carbon nanotubes (CNT), and graphene. In particular, epidermal electronics, a.k.a. electronic tattoos (e-tattoos) represent a class of noninvasive stretchable circuits, sensors, and stimulators that are ultrathin, ultrasoft and skin-conformable. My group has invented a dry and freeform “cut-solder-paste” method for the rapid prototyping of multimodal, wireless, or very large area e-tattoos that are also high-performance and long-term wearable. The e-tattoos can be applied for physiological sensing and prosthesis/robot control. Recently, we have also engineered e-skins based on electrically conductive porous nanocomposite. The hybrid piezoresistive and piezocapacitive responses of this novel e-skin has enabled high pressure sensitivity over wide pressure ranges. It therefore could be applied for not only mechanophysiological sensing, but also soft robotics undergoing large deformations. A perspective on future opportunities and challenges in this field will be offered at the end of the talk.
