Title
Flexible optoelectronics for power transfer through soft live tissues, and their shape control

Speaker

Abstract
Electronic implants that provide exceptional functions usually require more electrical power, resulting in shorter period of usages although many approaches have been suggested to harvest electrical power in human bodies by resolving the issues related to power density, biocompatibility, tissue damage, and others. In this talk, I will introduce an active optical wireless power transfer approach at the level of a full system to secure sustainable electrical power in human bodies. The active power transfer system consists of a pair of the skin-attachable photon source patch and the photovoltaic device array integrated in a flexible medical implant. Demonstrations will be shown to validate feasibility of the approach by presenting thermal and mechanical compatibility with soft live tissues while generating enough electrical power in live bodies through in vivo animal experiments. The second topic in the talk is about soft robotic flexible electronics. Mechanical flexibility introduced in functional electronic devices has allowed electronics to avoid mechanical breakage, conform to nonplanar surfaces, or attach to deformable surfaces, leading to greatly expanded applications, and some research efforts have already led to commercialization. However, most of these devices are passively flexible by external driving forces. In this talk, I will briefly introduce actively flexible soft robotic substrates that can serve as a platform for flexible electronics. Coordinated control policies are formulated to control multiple segments with independently controllable embedded actuators, based on localized proprioceptive self-sensing capabilities.
