Grip Strength Testing Device
Jan. 2019 - May 2019
Existing research has found that grip strength can vary widely as shoulder, elbow, and wrist position changes. Our group was interested to test this theory by building our grip strength testing device. We constructed our device using a load cell with strain gages to measure the displacement of the beam, an operational amplifier to amplify the voltage signal, and MATLAB GUI to display real-time plot and data. After calibrating our device, we then conducted the test and we concluded that people tend to have larger grip strength when the hand is above their head.
Gather Testing Data
We invited 20 of our friends to test their grip strength at different arm positions. We recorded and analyzed all the data. We then concluded that people tend to have more grip strength when their hand is above their head.
