2023 ACS Fall POLY: CME NASA Symposium Abstract

Bioelectronics Applications of Skin-Inspired Electronics

Skin-inspired electronics is emerging as a new generation of soft electronics that may allow intimate contact with biological systems with minimal mechanical damage. Furthermore, they allow sensing information with higher signal-to-noise ratio due to the lower impedance at electrode-tissue interface. In this talk, I will discuss several projects related to engineering conductive materials and developing fabrication methods to allow electronics with effective electrical interfaces with biological systems, through tuning their electrical as well as mechanical properties. The end-result is a soft electrical interface that has both low interfacial impedance as well as match mechanical properties with biological tissue. Several applications of such electronics will be presented.

2022 CME NASA Symposium Abstract

Engineering Soft Polymer Electronics for Bio Interfaces

Soft polymer electronics have several desirable features for bioelectronic interfaces. In addition to their ability to accommodate the dynamic movement and change in size due to grow of organ, the high surface area of conducting polymer hydrogel results in low tissue-electronics interfacial impedance. This enables low-voltage electrical stimulation and high-resolution electrophysiological recording. In this talk, I will present materials design, fabrication, and applications of soft polymer electronics for bio interfaces. Examples include morphing electronics, high-density electrophysiological mapping, and neural transmitter sensing.
