Problems solved by technology

Although the fabric pressure sensor array with this type of design has soft properties, its thickness is relatively large, which is not conducive to integrating it into common textiles in daily life; different layers of fabrics are formed by sandwiching and bonding with adhesive materials, and the interlayer The mechanical properties are poor, and the air permeability is poor; and there are cumbersome manufacturing processes, which are not easy to large-scale processing; in addition, the fabric that acts as a piezoresistive is a flexible large-area continuum, resulting in the existence of this type of fabric pressure sensing array. significant crosstalk

Embodiment 1

[0033] Figure 1-3 A schematic structural diagram of the fabric pressure sensing array 8 of this embodiment is shown. like figure 1 and figure 2 As shown, the fabric pressure sensing array 8 is composed of the base fabric 4, the first conductive yarn 1, the second conductive yarn 3, the first non-conductive yarn 7, the second non-conductive yarn 6 and the pressure sensing unit 2 . In the present embodiment, base fabric 4 has a grammage of 98.8g / m 2, Pure polyester plain woven fabric with a warp density of 150 threads / 5cm and a weft density of 150 threads / 5cm. The first conductive yarn 1 and the second conductive yarn 3 are located on the front side of the base fabric 4 , and the first non-conductive yarn 7 and the second non-conductive yarn 6 are located on the reverse side of the base fabric 4 . In this embodiment, there are 6 first conductive yarns 1 in total, arranged along the warp direction of the base fabric 4 , and adjacent conductive yarns are evenly arranged at ...

Embodiment 2

[0045] like Figure 7 As shown, a fabric pressure sensor array 8 provided in this embodiment is connected with a signal processing and control module 10 and a data storage and display module 11 to form a schematic diagram of a pressure distribution measurement system 12 . The difference between this embodiment and Embodiment 1 is that the data storage and display module 11 is a mobile terminal (which may be a mobile phone, a tablet computer, etc.). Wireless communication is performed between the wireless communication module 20 on the signal processing and control module 10 and the mobile terminal. The signal processing and control module 10 transmits the measured pressure value acting on the fabric pressure sensor array 8 to the mobile terminal through the wireless communication, and the mobile terminal stores the pressure value in the form of data, and stores the pressure value as form to display.

[0046] It can be seen that the fabric pressure sensing array of the presen...

Abstract

The invention relates to a fabric pressure sensing array. A plurality of first conductive yarns are arranged on the front surface of a base fabric at intervals along the first direction of the base fabric, and a plurality of second conductive yarns are arranged above the plurality of first conductive yarns at intervals along the second direction of the base fabric; pressure sensing units for realizing circuit conduction are arranged at intersections of the plurality of first conductive yarns and the plurality of second conductive yarns; a plurality of first non-conductive yarns are arranged on the reverse side of a base fabric at intervals in the first direction of the base fabric, and the first non-conductive yarns are in one-to-one correspondence with the first conductive yarns in position; a plurality of second non-conductive yarns are arranged above the plurality of first non-conductive yarns at intervals along the second direction of the base fabric, and are in one-to-one correspondence with the positions of the second conductive yarns. The invention also provides a manufacturing method of the fabric pressure sensing array and a distributed pressure detection system of the fabric pressure sensing array. According to the invention, the crosstalk effect can be reduced.

Description

technical field [0001] The invention relates to the technical field of textile and flexible electronics, in particular to a fabric pressure sensing array, a manufacturing method thereof, and a pressure distribution detection system. Background technique [0002] With the development of flexible sensors in the direction of integration and human-machine friendliness, fabric pressure sensors with force-sensitive response characteristics can convert pressure into electrical signals, and have excellent human-computer interaction comfort, environmental friendliness and economy. It is easy to integrate into people's living environment and build other electronic devices on the fabric substrate without interfering with people's daily life, so it has great application potential in environment-based sensing and monitoring. For example, Day et al. reported a common fabric pressure sensor array composed of five layers of fabrics. The middle layer is a piezoresistive fabric coated with pi...
