We have developed a magnetic grip-and-release motion detection system to measure time differences among fingers during motion. We designed a magnetic sensing system consisting of a magnetic oscillation coil, sensing coil, and circuit unit. We measured wave forms of grip-and-release motion (15 s) of seven healthy volunteers using the system. To provide the grip-and-release timing of each finger, we used the reference voltage of each subject in the state of grasping a rod with a 30 mm diameter. Using the reference voltage, the time differences in the finger movements of all volunteers were detected. The detected grip-and-release time difference of both dominant and nondominant hands had a main tendency in which the closing movement of the little finger is fast, within 10 ms, and the opening movement is slow, within 13 ms. Our data suggest that the new magnetic sensing system has the potential to detect the quantitative value of the time difference in grip-and-release motion among fingers.
