| Outline of Final Research Achievements |
This project aims to develop technologies for small-sized brain implantable microelectronics system for a long period monitoring of nervous systems. We have proposed very fine silicon needle electrode technology, which offers further low invasive electrode penetration compared to other conventional microdevices and enables stable recording for a long period (e.g. several months to a year). Based on the device technology, major achievements of the research during the project period include characterizations of the silicon needle electrodes for brain implantation, integration of the needle with MOSFETs, on-chip microsystem (amplifier, data/power wireless transmission system, and flexible antenna), and the in vivo animal tests. The proposed brain implantable microsystem could become a powerful technique to assist in a long period monitoring of nervous systems in medical applications.
