Design of Interactive Information System Based on Human Body Communication

In view of the connectivity problem among wearable devices,the interactive information system based on the human body communication is implemented.Considering the application scenarios of the wearable device,the bidirectional communication MAC protocols on the human body communication is designed.In order to promote the communication efficiency of the object,one kind of transmitting frame structure about human body communication is constructed.To reduce the power consumption of the system,three types of models for the system are designed.The results are proved that the scheme could finish information interaction immediately.Its data rate arrives at 200 kbit/s,and the bit error rate is 10~(-8).At the same time,this paper works laid a good foundation for IEEE 802.15.6 standard realization of MAC protocol,and it is further promoting the development of the technology and application on the human body communication.
