Three-dimensional force loading and calibration device of flexible touch sensor

The invention belongs to a testing technology of a sensor, and particularly relates to a three-dimensional force loading and calibration device of a flexible touch sensor. The three-dimensional force loading and calibration device comprises an operating floor and clamping mechanism for placing a sample, a force loading device and control mechanism, a direction and angle adjusting mechanism, and a support frame. The force loading device and control mechanism is a pneumatic power mechanism formed by a force loading rod, a pull pressure sensor, a mini cylinder, an air pressure adjusting valve and air source and an electric control box, or is an electromagnetic force mechanism formed by a force loading rod, a pull pressure sensor, a voice coil motor, a current controller and an electric control box. The support frame is a simple support or an X-Y-Z liner motion three-dimensional support frame formed by a mechanical motion pair. The force loading device is arranged on the support on an operating floor directly or
