Abstract

Abstract: A fully flexible force position sensor's design, modeling and manufacturing method are introduced in this article, and the experimental verification is carried out. The sensor can be used to measure the force or displacement by attaching to the surface of the object or embedding it inside. First of all, the wire drawing molding method of micro manufacturing is introduced into the structure of the software innovatively, construction of low cost, easy to realize the software of micro channel forming process system, verify the advantages of the process in the forming of the micro channel software by comparison, the high performance and rapid manufacturing of the full flexible sensor has been achieved successfully. Secondly, based on the method, a double layer parallel multi strip micro channel sensor structure is designed, which effectively improves the sensitivity and linearity. The performance of the sensor has been verified through experiments. When the elongation is less than 14%, as a full flexible force sensor, the linear error is less than 5%, and the sensitivity is 16.95 mV/N. As a full flexible displacement sensor, the linear error is less than 2%, and the sensitivity is 5.56 mV/mm. The research content has great reference value for the structure design and forming method of the full flexible sensor in practical application.

Key words: force or displacement perception, fully flexible sensor, liquid metal, wire drawing molding method
