A Personalized Electronic Tattoo for Healthcare Realized by On‐the‐Spot Assembly of an Intrinsically Conductive and Durable Liquid‐Metal Composite (Adv. Mater. 32/2022)

Abstract

E-Tattoos In article number 2204159, Hyung-Ryong Kim, Jae-Woong Jeong, Steve Park, and co-workers introduce a new class of e-tattoo that can be implemented on-the-fly according to users' demands. To realize intimate, compact, and rapid assembly of intrinsically conductive and durable EGaIn composites, ethanol-based ink is developed. Demonstrations of wearable bioelectronics confirm the validity of the e-tattoo in healthcare.
