Abstract

Wireless wearable sweat analysis devices can monitor biomarkers at the molecular level continuously and in situ, which is highly desired for personalized health care. The miniaturization, integration, and wireless operation of sweat sensors improve the comfort and convenience while also bringing forward new challenges for power supply technology. Herein, a wireless self-powered wearable sweat analysis system (SWSAS) is designed that effectively converts the mechanical energy of human motion into electricity through hybrid nanogenerator modules (HNGMs). The HNGM shows stable output characteristics at low frequency with a current of 15 mA and a voltage of 60 V. Through real-time on-body sweat analysis powered by HNGM, the SWSAS is demonstrated to selectively monitor biomarkers (Na and K ) in sweat and wirelessly transmit the sensing data to the user interface via Bluetooth.

摘要

无线可穿戴汗液分析设备能够在分子水平上连续、原位地监测生物标志物，这对于个性化医疗保健来说是非常需要的。汗液传感器的小型化、集成化和无线操作提高了舒适度和便利性，但同时也给电源技术带来了新的挑战。在此，设计了一种无线自供电可穿戴汗液分析系统（SWSAS），该系统通过混合纳米发电机模块（HNGM）有效地将人体运动的机械能转化为电能。HNGM在低频下表现出稳定的输出特性，电流为15毫安，电压为60伏。通过由HNGM供电的实时体表汗液分析，SWSAS被证明能够选择性地监测汗液中的生物标志物（钠和钾），并通过蓝牙将传感数据无线传输到用户界面。
