specific Embodiment approach

[0043] The specific implementation method is: add 10 grams of carbon black particles into 50 grams of n-hexane solution, fully stir until uniformly dispersed, then put the laser-cut porous structure unit into the solution, make it fully soaked, and finally soak the conductive The porous structure unit of the solution can be dried in an oven or on a heating platform.

[0044] The flexible porous sensing unit 40 and the silicone gas chamber 50 with variable air pressure can be arranged in the mold to personalize the arrangement. The flexible porous sensing unit 40 and Density and arrangement of silica gel air chambers 50 with variable air pressure.

[0045] The arrangement of flexible porous sensing units on the variable stiffness sensing array device based on porous structure and flexible material includes but not limited to 4×4 array, and the higher order array structure is the same. A higher-order array structure has more flexible porous sensing units 40, which can realize a...

Abstract

The invention discloses a variable stiffness sensing array based on a flexible porous material. The sensing array comprises a dynamic micro-force flexible sensing layer, a static force flexible sensing layer and a packaging layer. The dynamic micro-force flexible sensing layer comprises a flexible porous sensing thin layer prepared by mixing the flexible porous material and a sensitive conductivematerial, and a corresponding conductive electrode; the static force flexible sensing layer comprises flexible sensing units, silica gel air chambers and a flexible substrate wrapping the flexible sensing units and the silica gel air chambers and playing a role in connection; two output ends are led out to serve as electrical signal transmission channels after two ends of all the flexible sensingunits are connected in series, and breather pipes penetrate through the bottoms of all the silica gel air chambers. The packaging layer is composed of a textile thin layer sprayed with an insulating material. The sensing array disclosed by the invention has the functions of adjustable sensitivity and adjustable rigidity of the sensing array; the silica gel air chambers and the flexible porous material have the advantages of safety, buffering and energy absorption, and also have the characteristics of replaceability and personalized installation.

Description

technical field [0001] The invention relates to a sensing device, in particular to a variable stiffness sensing array based on flexible porous materials. Background technique [0002] At present, with the development of modern technology, the emergence of robots has solved many problems in industrial production. In the context of continuous technological advancement and rising labor costs, robots have gradually moved from industrial production to people's daily life. In this case, there will inevitably be interactions between robots and humans, and between robots and the environment. [0003] In the process of human-robot interaction, the safety of the interaction is of paramount importance. In safety considerations, accidental collision is a key issue that cannot be ignored. Robots that can truly integrate into human life and work collaboratively with humans must have the ability to complete expected collaborative actions in complex dynamic unstructured environments and i...
