[0002] A force sensor is a device that can sense and measure force. It can convert the sensed mechanical quantity (such as tension, tension, pressure, weight, torque, internal stress and strain, etc.) into corresponding electrical signal output. This conversion allows the size of the force to be quantified, transmitted, processed and recorded through electrical signals, thereby achieving accurate measurement and control of the force.

[0003] After the force sensor is used for a period of time, its performance needs to be calibrated to ensure normal use of the force sensor.
