Problems solved by technology

Among them, RSscan is based on the principle of resistance strain bridging, with a hard substrate, limited use occasions, and its sensor has a short life span. Regardless of whether it is used or not, the sensor needs to be replaced every six months to a year, but it is very useful in software database functions. Features: Fuji film is a one-time chemical imaging scanning principle, the accuracy is less than 10%, and the cost of a single test is 300-500 yuan, which is suitable for one-time measurement

Embodiment Construction

[0023] See Figures 1-4. The array sensor in Figure 1 prints the sensitive material onto two insulating substrates (polyester film) in a matrix, among which, one piece is connected in rows, that is, connected in 20 rows at a side of 20cm; the other one is drawn out in columns Shaped connection, that is, connected into 40 columns, divided into two 20-line leads on the 20cm side. According to the analysis of the scanning driving principle, in order to be as close to the ideal state as possible, the on-resistance of the two-choice one-column switch must be as small as possible, and ADG719 is selected. The nominal maximum on-resistance of the chip: 4Ω@5V / 10Ω@3V, 200M-3Db bandwidth. ADG708 is selected as the multi-choice row switch, the nominal typical on-resistance: 3Ω@5V / 8Ω@3V, 55M-3Db bandwidth.

[0024] The flexible array sensor (1) is composed of two laminated polyester film substrates (1-1), each layer of polyester film substrate (1-1) is printed with a pressure sensor circu...

Abstract

The invention provides a pressure distribution measuring device and a measuring method thereof. The pressure distribution measuring device consists of a flexible array sensor (1), an embedded signal drive collection unit (2) and computer analysis processing software (3). The embedded signal drive collection unit (2) has the function of scanning drive of array lines and rows, and the function of collection of pressure signals of array points. The embedded signal drive collection unit (2) is connected with a computer through a USB 2.0 interface. The computer analysis and processing software comprises a communication interface module, a data access module, a data analysis module, a records management module and a print driver module. The computer gets the information of the acting force, the distribution information of the acting force, the center of pressure, the information about the power spectrum and so on through collecting the information of the acting force output by the force sensor and the analysis software. The invention provides scientific basis for athletic research, instruction of athletic training, scientific research of medical treatment, disabled body recovery training instruction and so on.

Description

technical field [0001] The invention relates to the field of sensor application technology, and belongs to a measuring instrument and a measuring means in the field of sports scientific research, biomechanical engineering, medical rehabilitation, and industrial measurement, and in particular relates to a pressure distribution measuring device and a device for gait analysis and industrial measurement. Measurement methods. Background technique [0002] In the fields of sports research, biomechanical engineering, and medical rehabilitation, it is often necessary to accurately know the force between the sole of the human body and the ground, the contact between the sole of the foot and the storefront, and the distribution of pressure on the sole of the foot when the human body is walking or exercising. , in order to obtain the scientific basis for sports research, sports training guidance, medical research, and rehabilitation training guidance for the disabled. The pressure dis...
