Abstract :
A tactile imaging sensor that quantifies and displays the mechanical properties of the touched objects, was developed. This tactile imaging sensor provides the applied force using the sum of the pixel values. A linear regression model was used to calibrate the sensor. A tissue phantom experiment was performed to validate the calibration. The estimation error was found to be 0.6 to 7.2%.
