▎ 摘  要

NOVELTY - The sensor has a polyethylene foam acrylic double-sided tape substrate layer (1) whose opposite side is provided with a transferred laser-induced graphene electrode layer (2). Both ends of the laser-induced graphene electrode layer are connected with the conductive copper foil pins (3). The polyethylene foam acrylic double-sided tape substrate layers are adhered to each other and perpendicular to each other. The laser-induced graphene electrode layers are perpendicular to each other and attached to each other, which can provide multi-directional strain sensing capability. USE - Cross-shaped structure integrated multidimensional strain sensor used as robust development flexible, telescopic device used in medical diagnosis, movement detection and man-machine interaction. ADVANTAGE - The sensor utilizes the double-layer laser-induced graphene to build a double-layer cross-shaped structure, and generates the laser-induced graphene by UV laser ablation of polyimide film, so that the substrate layer is polyethylene foam acrylic double-sided tape. The sensor designs the graphene electrode in a specific shape, and transfers by polyethylene foam acrylic double-sided tape. The conductive copper foil is cut into a specific shape by the laser, and attached to the polyethylene foam substrate graphene electrode. The double-layer polyethylene foam-based graphene electrodes are vertically attached to each other to construct a double-layer cross-shaped multi-dimensional strain sensor. The sensor can monitor the multi-directional strain by measuring the resistance between the adjacent electrode pins of the sensor. The sensor has stronger tensile and compressive deformation performance, and provides multi-direction strain sensing ability. The sensor simplifies the material preparation process, reduces the environment pollution caused by the material preparation, and improves manufacturing efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a cross-shaped structure integrated multidimensional strain sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a cross-shaped structure integrated multidimensional strain sensor. 1Polyethylene foam acrylic double sided tape substrate layer 2Laser induced graphene electrode layer 3Conductive copper foil pin
