Wearable bioelectrode for electrophysiology monitoring
Yuhan's research interests include physiological and physical sensors for biosystems and system integration. She has worked on flexible potentiometric, resistive, and optical sensors for monitoring pressure, body temperature, pulse rate, and breathing patterns. Wet electrode has been the gold standard and most traditional method for monitoring electrophysiology. Yuhan's current work explores other forms of preparation-free electrode including semi-dry hydrogel electrodes for scalp EEG and dry CNT electrode for GSR, ECG/EMG/EOG applications, with low contact impedance, high biocompatibility, easiness to wear and take off, and high signal fidelity compared to the gold standard wet electrodes. She is passionate about bettering the electronic-human body interface by incorporating biocompatible materials that are flexible or stretchable and engineering their sensing-relevant properties. Her research on conductive transparent CNT electrode has other applications in optoelectronic devices such as OLED, OPV, and smart window.
