Embodiment Construction

[0021] Such as figure 1 , 2 As shown, a strain-type flexible breathing sensor for electronic fabrics of the present invention mainly includes a sensor sensitive element 1 of a plain weave structure woven by elastic conductive fibers 11 and insulating fibers 12; the conductive fibers 11 are selected from carbon nanotubes Modified polyurethane fibers with a resistivity of 10 8 Ω cm, the insulating fiber 12 is made of ordinary polyurethane fiber; the weaving method is adopted, wherein all the warp yarns are insulating fibers 12, part of the weft yarns are conductive fibers 11, and part of the weft yarns are insulating fibers 12, and there are two adjacent conductive fibers 11. Insulating fibers 12; the conductive fibers 11 at the edge of the sensor sensitive element 1 are connected in series in the form of folded lambda edges to form a continuous conductive fiber 11; the two ends of the continuous conductive fiber 11 have lead wires or wires for electrical connection Connector ...

Abstract

The strain-type flexible respiration transducer for electronic fabric includes transducer sensing element in the form of fabric comprising elastic conducting fiber and insulating fiber, and the transducer sensing element has lead or joint for electric connection. The clothing with the respiration transducer for monitoring the respiration of the human body is one maillot with at least one of this flexible respiration transducer in the chest part. The flexible respiration transducer and the clothing with the flexible respiration transducer may be bent, folded, kneaded and washed, are suitable for monitoring the respiration information in the worn state, and have simple structure, low cost and convenient use.

Description

technical field [0001] The invention relates to a flexible breathing sensor, in particular to a conductive fiber-based flexible sensor for detecting physiological information of a human body. Background technique [0002] Prior to this, many patents have been published on the use of conductive fibers for fabrics or clothing to detect physiological information (such as body temperature, heart rate, electrocardiogram, pulse, respiration, etc.) of the human body. In these patents, conductive fibers have the role of information transmission or power supply. For example, the fabrics or clothing disclosed in Chinese patents 99801099.5 and 00811968.6 granted to Georgia Technology Research Corporation of the United States include conductive fibers for information transmission or power supply. The electrode sensor disclosed in Chinese patent 03804817.5 granted to Royal Philips Electronics Co., Ltd. of the Netherlands includes conductive fibers used as a support for connecting electr...
