Design and Evaluation of a Fiber-Optic Grip Force Sensor with Compliant 3D-Printable Structure for (f)MRI Applications

Figure 8

Grip force sensor response to a force step from 0 to 500 N within 0.2 s and from 500 to 0 N. The dashed line represents the applied force by the material testing machine, and the solid line represents the estimated force based on the sensor reading and sensitivity.
