Lattice type flexible pressure distribution sensor and manufacturing method thereof

Abstract

The invention relates to a lattice type flexible pressure distribution sensor and a manufacturing method thereof. The lattice type flexible pressure distribution sensor comprises a first flexible substrate and a second flexible substrate, wherein the first flexible substrate is provided with a line electrode; the line electrode is covered with line electrode force-sensitive printing ink which is electrically connected; the first flexible substrate is provided a line leading-out electrode corresponding to the other end provided with the line electrode; the second flexible substrate is provided with a row electrode; the row electrode is covered with row electrode force-sensitive printing ink which is electrically connected; the second flexible substrate is provided with a row leading-out electrode corresponding to the other end provided by the row electrode; one end of the first flexible substrate which is correspondingly provided with the line leading-out electrode is bonded and fixed with one end of the second flexible substrate which is correspondingly provided with the row leading-out electrode after insulating, so that the line electrode and the row electrode are distributed longitudinally and transversally in a staggered way; and the line electrode is contacted with the row electrode force-sensitive printing ink of the row electrode through the line electrode force-sensitive printing ink. The lattice type flexible pressure distribution sensor has the advantages of compact structure, high detection precision, adaptability to the detection requirements of complex surfaces, wide application range, safety and reliability.

Description

technical field [0001] The invention relates to a pressure distribution sensor and a preparation method thereof, in particular to a dot-matrix flexible pressure distribution sensor and a preparation method thereof, belonging to the technical field of pressure distribution sensors. Background technique [0002] The study of contact stress is a hot topic in engineering and mechanics. Scholars at home and abroad have made some arduous discussions on the flexible and rigid contact between the surfaces of two objects, especially every small contact point and subtle stress effect on the contact surface. , and obtained a lot of theoretical analysis results, including patent documents. Although theoretical analysis such as the above-mentioned patents seems to be well-founded, it is difficult to apply quantitatively to practical problems. [0003] In the 1980s, foreign countries began to study tactile arrays for detecting contact points and areas, contact cross-sectional shapes, and...

Problems solved by technology

For example, the patent application CN101669018A discloses a pressure sensor using carbon nanotubes. Its structure is to embed a carbon nanotube composite in the gasket, and use three electrodes of source, drain and gate to sense the resistance that occurs when pressure is applied. Rate changes, this structure is complex in technology and poor in practicability
