Multifunctional Liquid Metal–Hydrogels
by Liquid Metal-Hydrogel Composites
Conductive Soft Hydrogels
This research focuses on the development of multif unctional liquid metal incorporated–hydrogel systems that combine softness, stretchability, and electrical conductivity. These soft materials enable stable and conformable interfaces for wearable bioelectronics and superior electrophysiological monitoring. Beyond bio–interfaces, our work extends to soft electronics and energy storage systems, opening new pathways for adaptive, durable, and multifunctional soft devices.
Stretchable Liquid Metal-Hydrogel Ionic Diodes for Soft Semiconductor Electronics
Stretchable liquid metal-hydrogel ionic diodes create flexible "Soft Semiconductors" by combining liquid metals with biocompatible gels, mimicking traditional diodes but bending and stretching like skin without breaking. Unlike rigid silicon chips, these devices enable wearable electronics that conform to the body for health monitoring or soft robots. Our research advances this by establishing liquid metal interfaces on hydrogels to improve device performance and durability for real-world bioelectronics. This contributes to the semiconductor industry by pioneering sustainable, body-friendly alternatives to brittle components, opening markets in flexible wearables, implants, and human-machine interfaces.
Liquid Metal-Hydrogel Composite Electrodes for Electrophysiological Monitoring
Liquid metal-hydrogel composite epidermal electrodes advance electrophysiological monitoring by integrating liquid metals with soft biocompatible hydrogels. These stretchable materials conform seamlessly to skin, providing stable low-impedance contact for electrocardiogram (ECG) and electromyogram (EMG) signal acquisition. Unlike rigid conventional electrodes, they eliminate motion artifacts and enable comfortable, prolonged wear for continuous health tracking. Our research utilizes liquid metal-hydrogel composites, developing functional e-tattoo prototypes that have potential in reliable biosensing performance for clinical diagnostics, fitness monitoring, and wearable healthcare applications.
