PhotoElasticFinger: Robot Tactile Fingertip Based on Photoelastic Effect
The sensor measures the force based on the PhotoElastic effect observed in the silicone matter. The polarized light within the silicone rubber is subjected to the phase-shift when the silicone is pressed. Force estimated is proportional to the light received by the camera.
