摘要

Wearable electronics play important roles in noninvasive, continuous, andpersonalized monitoring of multiple biosignals generated by the body. Tounleash their full potential for the next-generation human-centered bio-integratedelectronics, wireless sensing capability is a desirable feature. However,state-of-the-art wireless sensing technologies exploit rigid and bulky electronicmodules for power supply, signal generation, and data transmission.This study reports a battery-free device technology based on a “two-part”resonance circuit model with modularized, physically separated, and detachablefunctional units for magnetic coupling and biosensing. The resultingplatform combines advantages of electronics and microfluidics with low cost,minimized form factors, and improved performance stability. Demonstrationof a detachable sweat patch capable of simultaneous recording of cortisolconcentration, pH value, and temperature highlights the potential of the“two-part” circuit for advanced, transformative biosensing. The resultingwireless sensors provide a new engineering solution to monitoring biosignalsthrough intimate and seamless integration with skin surfaces.
