| Abstract Scope |
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 the skin-like, multifunctional electronic skins and tattoos using standing enokitake mushroom-like vertically aligned nanowire. 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 discuss our newly developed standing gold nanowire-based soft biosensing platform in the forms of patches, fibers and tattoos. Combining it with local cracking technology, we can arbitrarily fine-tune desired sensitivity and stretchability of a gold nanowire electronic tattoos by programming localized crack size, shape and orientations. Furthermore, we demonstrate in-plane integration of strain/pressure sensor, anisotropic orientation-specific sensors, strain-insensitive stretchable interconnects, temperature sensors, glucose sensors, and lactate sensors without the need of soldering or gluing. |
