Miniature Force Sensor based on Dual-photointerrupter with High Linearity and Disturbance Compensation

This paper presents a photointerrupter based force sensing mechanism to implement a low-cost, high accuracy, and reliable sensor with a miniaturized design. In previous literature, photointerrupter based force sensors have demonstrated a reasonable performance in a cost-effective manner, but have a narrow range of linear output and are significantly susceptible to external disturbances. This makes...
