Abstract

The invention provides a pair of multi-physiological-parameter monitoring intelligent bras integrated with a textile sensor and a manufacturing method of the multi-physiological-parameter monitoring intelligent bras. The bras comprise bra bodies, a micro data processing device, textile structure flexible electrocardio-electrodes, a textile structure flexible breathing electrode and a textile structure temperature sensor which are connected, wherein the micro data processing device is separately connected with the textile structure flexible electrocardio-electrodes, the textile structure flexible breathing electrode and the textile structure temperature sensor; the micro data processing device is detachably mounted on a heart position of the bra bodies; the textile structure flexible electrocardio-electrodes are arranged on cotton cloth at the inner side of cups of the bra bodies; the textile structure flexible breathing electrode is arranged on a rubber band of lower parts of the bra bodies; and the textile structure temperature sensor is arranged on shaped gauze of the inner layer of the heart of the bra bodies, and is in direct contact with wearer skin. According to the bras provided by the invention, conductive yarns are directly woven or ambroidered into fabric, does not need conductive treatment, so that the bras have the advantages of no coatings, softness, skin friendliness and the like.

Description

technical field [0001] The invention belongs to wearable devices, and in particular relates to an intelligent bra with integrated textile sensors for monitoring multiple physiological parameters and a preparation method thereof. Background technique [0002] Clothing has the closest contact with the human body and is the best platform for human body signal collection. Moreover, in the process of collecting physiological signals of the human body, the electrodes are required to be in close contact with the surface of the human body, have a certain pressure, and are not easy to shift during exercise. Therefore, tight-fitting underwear such as bras and shaping underwear known as the "second skin" of the human body have become one of the best carriers for wearable human physiological medical monitoring. In recent years, researchers at home and abroad have done a lot of wearable human physiological monitoring research on clothing products such as bras. At present, the monitorin...

AI Technical Summary

Problems solved by technology

The invention can effectively monitor the characteristics of breast lumps in the early stages of breast cancer, and can obtain timely treatment. At the same time, vibration sensors are used to monitor the syncope caused by breast cancer metastasis, which can easily cause patients to fall (disadvantage: graphene material Expensive, poor firmness, high production cost, unable to market the product)

(2) Chinese patent CN107280649A (application number 201610191772.7) discloses an intelligent wearable heart rate ECG monitoring device, including heart rate ECG acquisition electrodes, a control host and a bra carrier, and the conductive fiber yarn of the heart rate ECG acquisition electrodes is sewn In the lower area of ​​the bra, the heart rate ECG acquisition electrodes include three electrodes, and the three electrodes are connected to the control host; the control host includes a shell, a battery, a control board, and a heart rate ECG measurement module and a Bluetooth module are arranged on the control board , temperature measurement module, pedometer sensor and charge and discharge control circuit (disadvantage: the ECG acquisition electrode is on the lower edge of the bra, which is not the best position for collecting ECG signals)

According to the relationship between menstruation and basal body temperature, the liquid crystal thermometer is creatively combined with underwear, so that the change of basal body temperature can be measured conveniently and timely, and the arrival of menstruation can be predicted more accurately, which reduces worries and troubles. Changes pay attention to the abnormality of the body, so as to better maintain physical health (disadvantages are: the electrode base material for monitoring body temperature is a dark buckle or Velcro, which is difficult to guarantee softness and comfort; the monitoring thermometer is a liquid thermometer, and it is located in the groin. break easily when

In this invention, a massager, a temperature sensor, and a microprocessor power supply are provided. The flexible laminated battery or the wound battery is placed at the position of the back pull tab of the bra. Slotted holes on the upper surface of the active material layer and the lower surface of the conductive substrate (disadvantage: during the movement of the bra, the deformation of the rear tab is relatively large, which may easily cause the conductive substrate connected to the circuit to break or deform, affecting power supply or signal acquisition)

[0014] (1) The temperature adopts a large-area printed sensor, which is located in the inner layer of the clothing. The printed coating material is in direct contact with the skin, which is likely to cause skin allergies; at the same time, the coating material is printed on a high-elasticity (in this patent, in order to realize the close integration of clothing and the human body) , the spandex content of the fabric used is required to be more than 20%) clothing fabrics are easy to crack during wearing, which affects the temperature measurement effect; coating materials are not washable

[0015] (2) The textile structure flexible sensor for measuring ECG is embroidered between two layers of fabrics, without direct contact with the skin, which has a great influence on the acquisition of ECG signals

[0016] (3) The ECG signal is susceptible to noise interference, so the ECG signal acquisition electrode must be fixed at a position close to the heart

The carrier of the signal collection in this patent is ordinary underwear, which may easily cause the shift of the ECG signal collector during relatively high-intensity exercise and affect the collection of ECG signals

[0017] (4) Use the impedance method to monitor the respiratory signal. According to the research (Han Xiao's master thesis "Intelligent Monitoring of Seamless Underwear with Integrated Flexible Knitted Sensors" found the relationship between fabric strain and resistance: when other conditions are the same, the sensor The resistance value and sensitivity increase with the increase of the number of longitudinal rows, and increase with the decrease of the number of rows) The electrode for collecting the respiratory signal needs to have a certain length. In the above invention, the ECG sensor and the respiratory sensor are integrated. Affected by the fact that the electrode area of ​​the ECG sensor should not be too large, the respiratory signal sensor lacks sensitivity when collecting signals

[0018] (5) The LED display is located on the cuff of the underwear, and the connection line to the central processing unit is long, and it is easy to cause line failures such as breakage during clothing wearing, sports or washing
