Embodiment 1

[0079] A wearable breathing detection device provided in this embodiment is made according to the following steps:

[0080] (1) Preparation of graphene oxide solution: add 2 g of sodium nitrate to 120 ml of concentrated sulfuric acid, stir magnetically for 5 minutes, add 4 g of graphite powder, and stir magnetically for 30 min. Then slowly add 20g of potassium permanganate, and stir in an ice-water bath for 1.5h. The reaction system was naturally reacted at 35°C for 12 hours, 90ml of ice water was added, the temperature was controlled at about 45°C, magnetically stirred for 1.5h, and then 700ml of deionized water was added to the beaker. Finally, hydrogen peroxide was added dropwise until the solution was golden yellow. Wash by centrifugation until the pH of the solution is neutral to obtain a graphene oxide solution with a concentration of 6 mg / mL.

[0081] (2) Preparation of breath sensor 1:

Embodiment 2

[0091] The breathing detection device for women provided in this embodiment differs from that of Embodiment 1 in that:

[0092] Step (4) preparation of the wearable breathing detection device: as figure 2 As shown in the figure, polyester sewing yarn is used to sew the respiratory sensor 1 on the chest position of the commercially available women's sports underwear by flat stitch method, and the circuit board is placed between the clamp and the clamp in the middle of the tight belt by hot pressing method. In the accommodation space formed by the sports underwear, a wearable breathing detection device can be obtained.

Abstract

The invention provides a wearable breath detection device and a breath measurement method and relates to the field of intelligent wearing equipment. The device comprises a close-fitting garment body,a breath sensor and a signal processor. The breath sensor is fixed to the portion, corresponding to the chest, of the garment body and comprises a strain sensor body and electrode materials fixed to the two ends of the strain sensor body, wherein the strain sensor body comprises a conductive inner core and an elastic encapsulation layer. The signal processor is fixed to the garment body and used for converting signals output by the breath sensor into visual data. The device has the advantages of high fitting degree with the human body, simple structure and high sensitivity. The provided breathmeasurement method is simple and effective and can achieve real-time detection and acquisition of breath frequency and amplitude information of a tested person.

Description

technical field [0001] The invention relates to the field of smart wearable devices, and in particular to a wearable breath detection device and a breath measurement method. Background technique [0002] At present, the sensors for respiratory signal testing mainly include breathing mask sensors, or belt-type sensors made of hard materials, which do not conform to ergonomics, are large in size, are inconvenient to carry, and cannot realize real-time monitoring. Therefore, there is a need for a smart clothing that can directly detect breathing signals, is easy to carry, is practical and effective. [0003] Published wearable sensor fabrics or belts for detecting breathing signals are mainly based on sheet materials. For example, patents CN 107997768 A and CN 205568948 U disclose a method for converting the pressure signal generated by breathing into an electrical signal by a piezoelectric sheet, but the sensing sensitivity is not high. Moreover, additional strain gauges nee...
