System for Measuring Finger Force Profiles for Dexterity Assessment

摘要

We propose a novel system for measuring finger force profiles for dexterity assessment. Developed application controls turning on/off of LEDs (each LED corresponds to one finger) to signalize the user which finger should press the corresponding strain gage force sensor. Linearity, repeatability and sensitivity to position pressure of strain gage force sensors were tested to prove the system reliability. An example of potential usage of system with the assessment of quantitative parameters is presented.
