Abstract :
This paper describes a strain gauge-based sensor used for measuring finger force. The theory, design, and sensor construction details are presented. It was constructed using metallic strain gauges and a carefully designed structure which has a protection device that impedes the sensor damage when forces higher than 100 N are applied. Its dimensions are suitable for measuring thumb force, but the same design can be used for constructing smaller sensors for other fingers. It is rugged, presents linear response, good repeatability, resolution of 0.3 N, low hysteresis, and sensitivity of 0.12 V/N. It can be useful in rehabilitation engineering, biomechanics, robotics, and medicine
