A Wearable Sweat pH and Body Temperature Sensor Platform for Health, Fitness, and Wellness Applications

摘要

Wearable sensors development and diffusion on the market are in rapid expansion [1]. The medical community is particularly interested in the remote monitoring, as a result of budget reduction together with an increasing number of elderly and high-risk patients. Concerning fitness applications, the focus is on real-time monitoring of athletes' performances, in particular hydration and the sweat quality. The wellness field finally demands real-time data on personal health and environment. The wearable platform presented in this study (Fig. 1) is aimed to monitor the sweat pH and the skin temperature, by using novel high-resolution and accuracy techniques with ultralow power consumption. The sweat pH varies due to various endogenous and exogenous factors [2]. Skin temperature is linked to body thermoregulation [3], and its trend can provide information on the metabolic activity.
