On the other hand, telecommunication has wide applications in various fields. The objective of this study is to realize a sEMG-based wireless inte- raction control system. Method: According to the characteristics of sEMG signal, a record and am- plifier circuit was designed. The recorded sEMG is passing through a band pass filter. The feature of integration was calculated and transited into binary logical values. The obtained binary logical values were transferred to control module by using ZigBee technique. Finally, the interaction con- trol was realized. Results: Totally 4 healthy subjects with an average age of 20 years old were par- ticipated. The subjects were asked to do four kinds of hand movements and three channels of sEMG signals were recorded. Based on the testing results, the accuracy of control command ex- traction based on sEMG signal analys
