Title: Multiscale Sensing Technologies of Mechanical Interactions for Biomedical Applications
Abstract:  Force Sensing is quite important for mechatronic and information systems to detect and monitor mechanical interactions. Required force measurement range is quite large and we should design appropriate sensors based on the application. There are many force sensing methods. For example, we have developed a force sensor using a quartz crystal resonator (QCR) with a wide measurement range of 1.5 × 10e+6 (0.4 mN to 600 N). The proposed sensor allows a higher allowable force with high sensitivity. There are many new applications of force sensor having wide dynamic range. For example, it is effective for measurement of biosignals. Monitoring multiple biosignals, such as heart rate, respiration cycle, and weight transitions, contributes to the health management of individuals. Moreover, there are many new applications of force sensor in multiscale sensing range. Some of our research works on multiscale sensing and application examples are introduced especially for biomedical applications.
