An RFID Sensor with Microfluidic for Monitoring the pH of Sweat during Sport Activity

Among the multiple healthcare applications and systems exploiting sensing RFID boards, monitoring sweat's pH can be extremely useful for sportsmen and sportswomen. Furthermore, given the multiple known benefits that sports yield, measuring pH during physical activity can be integrated with points-of-care (PoCs) for patients who need working out. This contribution details the experimental testing of an RFID sensor for measuring sweat's pH during sporting activity. The electromagnetic (EM) performances are quantified over multiple wearers, and new, low-cost microfluidics made of absorbent paper is manufactured, characterized, and tested so that the use of the tag during exercise is proven feasible.
