Detection device for flexible force-induced discoloration material

The utility model relates to a detection device for a flexible force-induced discoloration material, and belongs to the technical field of stress sensors. The system comprises a stress control assembly and an optical path system. The structure of the stress control assembly comprises a tracking screw which is vertically fixed on the testing device; the first screw rod sleeve is connected to the tracking screw rod in a sleeving manner; the clamping plate consists of an upper clamping plate and a lower clamping plate, is fixed on the first screw sleeve, and is used for clamping a flexible force-induced discoloration material to be tested between the upper clamping plate and the lower clamping plate, and the flexible force-induced discoloration material is vertical to the horizontal plane; the stress sensor is arranged on the clamping plate and used for measuring the stress of the clamping plate when the clamping plate stretches the flexible force-induced discoloration material; the stretching motor is used for
