He has published >180 papers. He is currently the scientific editor for Nanoscale Horizon (Royal Society of Chemistry) and the editorial board members for a few journals including iScience, Chemosensors, Nanoscale, Nanoscale Advances, Advanced Sensors & Energy Materials, and Austin Journal of Biomedical Engineering.

Abstract for Presentation

Gold electronic skins and tattoos for connected healthcare

Sensitive, specific yet multifunctional tattoo-like electronics are ideal wearable systems for health monitoring anytime anywhere because they are virtually becoming parts of Human skins offering burdenless “unfeelable” wearing experience. Here, I will present our skin-like, multifunctional electronic skins and tattoos using standing enokitake mushroom-like vertically aligned nanowires. Among various materials of choices, gold has advantages of biocompatibity, chemical inertness, facile synthesis/Surface functionalisation and band-gap-matching with a lot of semiconductors materials. In this talk, I will briefly discuss our gold nanowire-based soft biosensing platform in the forms of patches, fibers and tattoos and cover some representative applications in health monitoring.
