Title:
SENSING ELASTIC FOAM AND MULTI-CHANNEL COAXIAL EXTRUSION ADDITIVE MANUFACTURING DEVICE AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/126943
Kind Code:
A1
Abstract:
A sensing elastic foam (10), which is an elastic dielectric unit and is formed by stacking porous meshes of greater than or equal to three layers. Each layer of porous mesh is formed by interweaving core-shell line structure units, and each core-shell line structure unit comprises an elastic line unit (101), a sensing unit (102), and a wire unit (103); the sensing unit (102) and the wire unit (103) are the core, and the elastic line unit (101) is the shell. Also disclosed are a multi-channel coaxial extrusion additive manufacturing device, a line mode transformation and adjustment method using the multi-channel coaxial extrusion additive manufacturing device, and a preparation method for the sensing elastic foam (10). The sensing elastic foam (10) is prepared by means of the multi-channel coaxial extrusion additive manufacturing device, and the purpose of switching and printing different line modes is realized by adjusting printing parameters online, thereby completing continuous manufacturing of different functional units (101, 102, 103) of the sensing elastic foam (10).
