Organic electronics, Organic bioelectronics, Soft electronics, Wearable biosensors

The goal of our research is to develop point-of-care and/or personalized medical devices to promote the healthcare revolution from “hospital-centric to human-centric” in the post-epidemic era. We focus on using emerging organic bioelectronic technologies for low-cost manufacturing of sensitive biosensors and “closed-loop” smart medical systems. Also, we develop soft microchips and memristors by using soft organic electrochemical transistors (OECTs) and soft iontronic hydrogels as game-changing building blocks. Meanwhile, we characterize and optimize the device performance, including their reliability and stability, and build novel soft circuits and architecture from the bottom up.
