| Outline of Final Research Achievements |
Purpose of this research is to obtain the technique of effective radio wave signal transmission among sensor nodes in body area network. We focused on the bio sensor network which consists of in vivo nodes. In vivo propagation model of radio wave and transmission method have been studied. Regarding the radio wave transmission, we have studied the typical propagation loss among in vivo nodes taking into account of the conductivity and permeability of the human muscle, bone, and organs. The latter problem attributes to the effective weak signal insertion into human body. Thus, we measured human body impedance of subjects by using network analyzer. According to the value of the measured impedance, we developed an insertion circuit which is operated by originally developed software. It is confirmed that the developed circuit operated properly. We published an article in the Neuroscience and Biomedical Engineering.
