Wireless, Flexible, Ionic, Perspiration‐Rate Sensor System with Long‐Time and High Sweat Volume Functions Toward Early‐Stage, Real‐Time Detection of Dehydration (Adv. Funct. Mater. 44/2023)

Perspiration-Rate Sensor System In article number 2306516, Kuniharu Takei and co-workers develop a wireless flexible and wearable sweat sensor patch by integrating sweat rate and electrolyte impedance sensors with long-time continuous measurement functions. Physiological response and rhythm of sweat electrolyte and sweat rate are successfully monitored under long-time sweating conditions, which can be only realized by continuous monitoring of trend changes of sweat.
