Abstract:
Soft electronics plays an important role in the realization of health monitoring and rehabilitation, Internet of Things (IoTs), and soft robotics. In the past two decades, the research focuses have been devoted to developing soft electronics based on thin film materials and architectures that are non-permeable to air, moisture, and liquid. It is recently found that permeability is essential to the chronic biocompatibility of these soft devices, especially those closely attached on soft skins and tissues. This short talk will discuss our recent research effort on developing liquid metal based soft and permeable electronics for wearable, skin-attached, and implantable applications. In particular, we will introduce how to fabricate stretchable and permeable electronics using liquid metal based material platform, and how to achieve high resolution patterning toward functional stretchable and permeable electronic devices and systems.
