Development of Bolt Type Force Sensor using Strain Gauges

- 1st Report : Study of Calibration Method -

Abstract

This paper proposes a new bolt type force sensor that measures forces applied to an object fixed by the sensor. This sensor consists of a general metal bolt and four strain gauges. Due to the feature of the bolt type sensor, it can measure the force applied to the object without extra jigs and gaps. In this report, the structure of the sensor is introduced and its calibration strategy is discussed. Finally, a force measurement experiment is conducted.
