Abstract

Abstract : Noninvasive Healthcare Monitoring In article number 2102740, Kilwon Cho and co‐workers report a sweat‐collecting patch with directional sweat transportation, enabling fast and continuous monitoring of sweat by a sensor. The wedge‐shaped wettability patterns of the patch are inspired by spines of cacti; the channel shape, in combination with the superhydrophobic/superhydrophilic surface materials, induces a unidirectional Laplace pressure that transports the sweat to the sensing‐area fast and spontaneously.
