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...
