摘要：
A novel self-powered wearable sweat-lactate analyzer for building sports big data has been realized basing on sweat-evaporation-biosensing coupling effect. The self-powered biosensor in analyzer is fabricated from porous carbon film (modified with lactate oxidase). The hydrophilic carbon can soak up sweat, and harvest environmental thermal energy to generate electricity through nature sweat-evaporation. The outputting voltage increases with increasing sweat-lactate concentration, which can be regarded as biosensing signal. The surface enzymatic reaction can change the zeta potential of carbon and thus influence the outputting voltage. On the flexible substrate, the biosensor can be integrated with wireless transmitter and capacitor, constructing a self-powered wearable sweat-lactate analyzer. The analyzer can detect sweat-lactate concentration on athlete's skin, wirelessly transmit the exercise physiological information to terminal, and build sports big data. This work can provoke a new research direction for realizing self-powered wearable exercise-analyzing system, and can also promote the development of sports big data.
