Self-Powered Wearable Sweat-Lactate Analyzer for Scheduling Training of Boat Race

Self-powered wearable sweat-lactate analyzer has been developed for training analysis of rowing. Tetrapod-shaped ZnO nanowires are attached onto ordinary textiles to form a device. Based on the coupling of enzymatic reaction (lactate oxidase and lactic acid) and piezoelectric effect, the device can be attached to the tester to monitor the driving frequency, rowing distance and sweat lactic acid concentration of the tester in real-time. The relationship between the rowing frequency and physiological state is obtained by monitoring the rowing process of the tester, which is helpful to formulate a training plan belonging to the rowing tester. This study provides a new direction for the scientific monitoring of kinematics and accelerates the development of wearable sports equipment.
