指輪型指先力センサの突起部の設計に関する研究

The ring-type sensor can measure tendon tension by pressing a protrusion into the finger and can estimate the fingertip force without interfering with fingertip sensation. The purpose of this study was to establish a design procedure for the ring-type sensor by examining the suitable pressing depth of sensor into the finger. In the experiment, for 6 subjects, we performed the indentation tests on the finger with applying fingertip force of 10 N and measured pressing depths and pressing forces on the fingers that the subjects felt uncomfortable. As the results, it was found that the use of the curved part of the sensor reduced the subject's discomfort. From the result, we established the design procedure to determine the suitable pressing depth of curved part and protrusion of sensor.
