In recent years, our society moves towards more and more aging society, and health care becomes one of the most important concerns. Since small-size wearable and implantable healthcare systems are required in aging society, the LSI technology becomes more important for biological information sensing. In this paper, we briefly summarize the fundamental biological sensing system, and introduce our current work, Medical Domain Specific SoC, Type I (MeSOC-I) for capsular inner bladder pressure sensing system. At the end of this paper, we sketch the future challenges for the biological information sensing.
