Abstract

The invention discloses an air pressure type flexible sensor array and an air pressure sensor unit thereof. The air pressure type flexible sensor array includes a first flexible substrate, a flexibleisolation layer and a second flexible substrate arranged in an overlapping manner. The surface of each of the first flexible substrate and the second flexible substrate adjacent to the flexible isolation layer is provided with at least one air groove. One end of each air groove is a first closed end while the other end is provided with an air pressure sensor unit in a sealed manner, so that each air groove forms a sealed space and each sealed space is provided with an inert gas. The extending direction of the air groove of the first flexible substrate intersects with the extending direction ofthe air groove of the second flexible substrate in a spatial perpendicular manner. According to the invention, the total pressure at a stress position and the surface distribution measurement can berealized, so that pressure mearuement from point measurement to face measurement is realized and pressure measurement precision and accuracy are improved. Besides, the array is simple in structure andlow in cost. Since the stress bodies are all made of flexible material, the array provided by the invention is good in flexibility and can be bent and the adaptability is high due to the irregular shaped surface.

Description

technical field [0001] The invention relates to the field of flexible pressure sensors, in particular to an air pressure flexible sensor array and an air pressure sensor unit. Background technique [0002] The measurement of contact pressure between objects and its pressure distribution plays an important role in the research and development of many industries, and is widely used in aerospace, machinery, electronics, sensors and other fields. With the rapid development of the Internet of Things, flexible pressure sensors are more and more frequently used in smart homes, smart wear, smart travel, medical health and other fields; for example, built-in pressure distribution sensors in car seat cushions measure sitting posture and viewing angle; Distributed sensors to monitor sleep conditions, etc. [0003] At present, there are many types of flexible pressure sensors, mainly divided into piezoresistive, piezoelectric, capacitive, optical sensing, magnetic sensing, pneumatic, e...
