a flexible capacitance and resistance sensor is studied, which is manufactured by single step using 3D printing technology of fused deposition molding. Compared with the existing manufacturing technology of flexible sensor, the 3D printing technology has the advantages of low manufacturing cost and simple manufacturing process. The capacitive force sensor and the resistance temperature sensor are fabricated by melting deposition and forming 3D printing respectively using the wires of conductive and dielectric materials. The capacitive force sensor adopts parallel plate structure, and its relative sensitivity can reach 0.088% / N. the relative sensitivity of the resistance temperature sensor can reach 2.2% / °C. The resistance and capacitance sensors can be used as touch sensors, which have great potential in the fields of electronic skin, intelligent wearable devices and soft robots.
