Abstract:

To resolve the problem of distinguishing acupuncture point for the unprofessional persons, we design a recognition and detection instrument with SPCE061A. The principles and diagrams of hardware and software architecture of the entire system are described. Based on theories of skin resistances on the acupoint resistance, a new acupoint detect instrument containing electrical stimulating is invented. The recognition acuracy on acupuncture and nonacupuncture can reach to 95% and 98%, respectively. Controlled through a MCU（Micro Control Unit）, the apparatus can output biphasic constant current and special pulses for electrical stimulation. The theory of meridians is significant for the basic theory of traditional Chinese medicine. The effects of environment on acupoint detection is discussed. Compared with the traditional method, this can improve and simplyfy the operation. 
