Dynamic Resistance Tester

The surface resistance of materials is typically measured using the four-probe method to determine the sheet resistance. For flexible electronic materials, such as coated materials and surface-conductive textiles, the magnitude of the pressure exerted by the four probes on the sample surface significantly affects the sheet resistance value. Furthermore, flexible electronic materials are easily deformed, and the sheet resistance changes after deformation. Therefore, based on the characteristics of flexible electronic materials, a dynamic sheet resistance tester has been developed and produced.
