  • Histological observation of titanium mesh electrode for transcutaneous information transmission using human body as conductive medium

抄録

We have developed a transcutaneous communication system using intrabody communication, and we proposed a titanium mesh electrode to obtain mechanically and electrically stable contact with tissue by inducing surrounding tissue. In this study, we studied histocompatibility of the titanium mesh with the inner wall of the thoracic cavity using a goat. A transmission current of 6 mA with a frequency of 4 MHz is within maximum allowable current applying a human body according to the ICNIRP guideline. However, the data transmission current had an effect on the tissue inside the titanium mesh, and more numbers of inflammatory cells were induced into the titanium mesh. The titanium mesh electrode on the internal communication unit was filled with more numbers of inflammatory cells rather than the titanium mesh electrode implanted alone. Stress inside the titanium mesh due to movement of the communication unit would evoke immune reaction, and it induced inflammatory cells into the titanium mesh. While physical stimuli such as stress and current would evoke week inflammatory immune response, the titanium mesh is suitable material for an electrode that can be implanted inside the body.
