| Outline of Final Research Achievements |
In order to perform the rehabilitation of a finger effectively, it is important to measure finger force of patients without inhibiting the grip sensation and to give appropriate advice using the force data. Therefore, in this project, we focused on the relationship between the tension of tendon and finger force, and proposed a ring type sensor that can estimate the finger force from tension of tendon. Availability of the ring type sensor to estimate finger force was verified experimentally. In experiments, strain output of the ring type sensor was measured during finger force applying to load cell increased. As a result, it was found that strain output increase with increase of finger force. From the results of the experiment, it was confirmed that it is possible to estimate the finger force by using the proposed sensor.
