Flexible sensing device for measuring head pressure and manufacture method thereof

Abstract

The invention relates to a flexible sensing device for measuring a head pressure and a manufacture method thereof. The flexible sensing device comprises a bottom silicon layer which can be fit to the curve shape of a head, the upper surface of the bottom silicon layer is provided with a matrix network which is formed by a plurality of pressure sensors and wires which are vertically and horizontally connected with the pressure sensors, and a power supply module for supplying electricity and an acquisition control module for outputting information of the pressure sensors are connected outside the matrix network through wires. The flexible sensing device has better flexibility, can be tightly clung to the curve face of the head, and is particularly suitable for measuring the pressures born on points of the head when a person wears protective articles such as a helmet and a safety helmet.

Description

technical field [0001] The invention relates to a flexible sensing device and a manufacturing method thereof, in particular to a flexible sensing device capable of accurately measuring head pressure when wearing protective headgear such as helmets and safety helmets and a manufacturing method thereof. Background technique [0002] Helmets and hard hats are all protective equipment used to prevent impact objects from hurting the head. With the increasing diversification of modern work and life, people pay more and more attention to life safety, and the use of head protection equipment is becoming more and more extensive, which can be roughly divided into three categories: military, work, and sports. Wearing protective equipment such as helmets and safety helmets can effectively protect life, but due to the special requirements for their performance, they all have considerable weight. For example, the weight of safety helmets stipulated by developed countries in the world gene...

Problems solved by technology

For a contact surface that is close to a plane, the traditional pressure sensor adopts a tiled layout method to complete the task well, but for a curved surface structure with a large curvature change, the traditional layout method is difficult to obtain accurate and reliable data

CN200710094157.5 proposes a device and measurement method for measuring the shape of the curved surface of the buttocks and its normal pressure distribution. It uses hydraulic connectors to obtain single-point or unevenly distributed pressure information, and it is difficult to form a regular matrix structure. It is not suitable for the measurement of pressure distribution on the top of the head; the utility model patent 200920080140.9 proposes a three-dimensional curved surface measurement device based on the pressure measuring plate, which uses the traditional layout method, does not have ductility, and is difficult to fit the curved surface closely, and is not easy to obtain the head Precise, reliable data on pressure
