Breathable Wearable Electronics by 3D Liquid Diode

Abstract

Wearable electronics, poised to revolutionize real-time health monitoring, encounter significant challenges due to sweat accumulation, including skin irritation, peeling, short circuits, and corrosion. A groundbreaking study published in Nature presents a sustainable solution: three-dimensional (3D) liquid diodes that effectively pump sweat away, thereby maintaining the wearables’ breathability and stable sensing of biometrics or environments without getting messed up by perspiration. This advancement has immense potential for the development of comfortable and skin-friendly intelligent wearable technologies that seamlessly incorporate sophisticated electronics even in sweaty conditions.
