Embodiment 1
[0047] Such as figure 1 and 2 As shown, a sensing elastic foam, the sensing elastic foam 10 is an elastic dielectric unit, which is formed by stacking no less than three layers of porous grids, and each layer of porous grids is formed by interweaving core-shell line structural units , the core-shell line structure unit includes an elastic line unit 101, a sensing unit 102 and a wire unit 103, wherein the sensing unit 102 and the wire unit 103 are cores, the elastic line unit 101 is a shell, and the sensing unit 102 is in The resistance, capacitance or inductance change significantly after being subjected to force deformation, heat or other external stimuli, and the resistance and the change of the wire unit 103 are smaller than the sensing unit 102, so the elastic foam can realize the sensing function.
[0048] The line width of the elastic line unit 101 is 1100 microns, and the wall thickness is 1100 microns; the line width of the sensing unit 102 is 1100 microns, the wall t...
Embodiment 2
[0071] A sensing elastic foam, the sensing elastic foam 10 is an elastic dielectric unit formed by stacking no less than three layers of porous grids, each layer of porous grids is formed by interweaving core-shell line structural units, the The core-shell line structure unit includes an elastic line unit 101, a sensing unit 102 and a wire unit 103, wherein the sensing unit 102 and the wire unit 103 are cores, the elastic line unit 101 is a shell, and the sensing unit 102 deforms under force. , heat or other external stimuli, the resistance, capacitance or inductance change obviously, and the resistance and the change of the wire unit 103 are smaller than the sensing unit 102, so the elastic foam can realize the sensing function.
[0072] The line width of the elastic line unit 101 is 1200 microns, and the wall thickness is 1200 microns; the line width of the sensing unit 102 is 1200 microns, the wall thickness is 300 microns, and the inner diameter of the inner core is 600 mic...
