Problems solved by technology

[0005] However, the existing knitted flexible sensors generally use the whole body of the sensor to be implanted into the target clothing, such as underwear or socks. This kind of manufacturing process is relatively complicated, and it is still not suitable for large-scale production at this stage.

Embodiment 1

[0038] A knitted flexible sensing device applied to clothing, comprising a circular moving sensing sheet, the moving sensing sheet is sequentially provided with a first knitted sensing layer 1, an insulating fabric layer 2 and a second sensing layer from the side close to the human body. 2 Knitted sensing layer 3 . The diameter of the mobile sensing sheet is 2cm to 10cm, and in this embodiment the diameter is 5cm. The mobile sensing sheet set at this size can complete the sensing function. If it is too large, it will waste materials, and if it is too small, it cannot be used normally. This range is just right.

[0039] First sensing wires 4 are interwoven in the first knitted sensing layer 1 , and the first sensing wires 4 are distributed inward in a helical shape. The second knitted sensing layer 3 is mixed with second sensing wires 5 , and the second sensing wires 5 are evenly and parallelly arranged. The first sensing wire 4 and the second sensing wire 5 are silver-plated...

Embodiment 2

[0048] Different from the first embodiment, the connecting part in the second embodiment adopts the following structure, the connecting part is an annular cloth 13 connected with the mounting piece 6, and the annular cloth 13 is connected with the garment through knitting. The device can be firmly fixed through the knitting connection of the annular cloth 13 and the garment, which is beneficial for long-term use.

[0049] In summary, the beneficial effects of the present invention are: (1) the sensing device can be easily installed to a designated location to measure corresponding physiological data, such as being installed at the heart and pulse, capable of measuring the beating of the heart, placed at the joint, It can measure the bending of joints, etc.; (2) the sensing device has good sensing accuracy, and its structure is relatively simple, easy to manufacture; (3) the connection between the sensing device and clothing is simple and fast, and it is suitable for different ...

Abstract

The invention discloses a knitting flexible sensing device applied to clothing. The knitting flexible sensing device comprises a moving sensing piece, wherein a first knitting sensing layer, an insulating fabric layer and a second knitting sensing layer are sequentially arranged; first sensing wires are knitted in the first knitting sensing layer in a mixing manner, and are spirally distributed inwards; second sensing wires are knitted in the second knitting sensing layer in a mixing manner, and are uniformly arranged; an annular mounting piece is connected to the moving sensing piece; a microsensing power source is arranged in the mounting piece; the micro sensing power source is connected with two ends of the first sensing wires to provide periodically-changed electric currents; a signal amplifier is arranged in the mounting piece; the signal input end of the signal amplifier is connected with a left half ring and a right half ring; the left half ring is connected with one ends of the second sensing wires, and the right half ring is connected to the other ends of the second sensing wire; and a signal processer and an output device are connected to the signal amplifier. Through the adoption of the knitting flexible sensing device disclosed by the invention, a target position can be sensed in details, and the knitting flexible sensing device has the advantage of being accuratein sensing.

Description

technical field [0001] The invention relates to the field of smart clothing, in particular to a knitted flexible sensing device applied to clothing. Background technique [0002] Clothing is a vital product in life. People's demand for clothing is not limited to hiding ugliness and keeping warm, but to pursue the functionalization, personalization and intelligence of clothing. Wearable smart clothing refers to the integration of electronic detection systems on clothing and its accessories, which can detect human physiological signals in daily wear and use. Clothing, as a "second skin", is in close contact with the human body. It has the advantages of lightness, comfort, portability, and large coverage. It is the best medium for obtaining human body signals. Knitted clothing, due to its special structure, exhibits the characteristics of softness, comfort, elasticity and flexibility, and is easy to be lined with conductive sensing materials. Therefore, it is often used as a ...
