About

Meihong Liao is a leading innovator in the field of flexible and transient bioelectronics, with a primary focus on wearable epidermal sensors and liquid metal-based hydrogels. Her most impactful contribution is the development of polyvinyl alcohol (PVA)-stabilized liquid metal hydrogels, which overcome critical limitations of traditional wearable sensors—namely, poor self-healing and non-dissolvable features. This breakthrough, detailed in her highly cited 2019 paper (240 citations), enables the creation of transient epidermal sensors that are both stretchable and fully dissolvable after use, addressing key challenges in sustainable healthcare monitoring and flexible touch displays. Liao’s work uniquely integrates materials science and biomedical engineering, offering a paradigm shift toward eco-friendly, disposable electronics. Her research has been widely recognized for its potential in human activity monitoring and implantable devices, with her 2019 study serving as a foundational reference in the field. By combining liquid metal conductivity with hydrogel biocompatibility, Liao has paved the way for next-generation wearable technologies that are both high-performance and environmentally benign.
