The graph above shows the linearity of the flex sensor in a normal circuit with a servo motor. In this circuit, the sensor is alone, showing that it works properly and can be used in the gripper.
This graph shows flex position over time, with the blue line being for no manipulation (control), the red line being for the contours of the gripper, and the yellow line being for the contours of the human hand. Without manipulation, the flex resistance does not change at all, which is expected. The gripper and hand both fluctuate wildly, but they both cover the same range. This means that the gripper can "flex" to any position the human hand will normally, showing that the flex sensor will work properly with the gripper for patients with neuropathy.
