The invention provides a wearable sweat detection system and method and wearable equipment. The wearable sweat detection system comprises a micro-fluidic chip, an electrochemical electrode, a circuitacquisition system and a mobile terminal system, wherein a sweat collecting part is arranged on the side, attached to the skin, of the micro-fluidic chip; a sweat concentrating cavity is formed in theother side of the micro-fluidic chip, and the sweat concentrating cavity makes contact with the electrochemical electrode; the circuit acquisition system converts electric signals of sweat componentsdetected by the electrochemical electrodes into digital signals and sends the digital signals to the mobile terminal system; and the mobile terminal system receives the digital signals, analyzes andprocesses the digital signals and then outputs sweat detection results. According to the wearable sweat detection system and method and the wearable equipment, operation is easy, carrying is convenient and fast, sweat of a tested person can be collected, detected, analyzed and output in real time, and therefore human health state information is monitored in real time and early warned in time.
