Problems solved by technology

The resistance distribution of the device manufactured in this way is affected by the precision of the process and has a large discreteness. When the substrate undergoes a large tensile deformation, the percolation network may be damaged, and the electric heating performance will be seriously reduced or even invalid. Adapt to the wearing needs of key thermal therapy parts such as human joints
In addition, factors such as the large size of the control system and complex transmission cables / wires are also important factors that prevent the existing thermotherapy devices that support constant temperature control from being applied to the wearable field.

Embodiment 1

[0026] Embodiment 1: An intelligent flexible wristband is provided in the embodiment of the present invention, such as figure 1 As shown, it includes a flexible heating element 1 , a wireless communication device 8 for intelligent temperature control, and a user terminal 9 . The flexible heating element 1 includes a vent hole 2, a polydimethylsilane (PDMS) flexible substrate 3, a silver nanowire (AgNW) heating function layer 4 and a PDMS protective layer 5. The flexible heating element 1 is embedded with a temperature sensing unit 6 and Heating electrode 7. The wrist brace is worn on the wrist to provide heat therapy for the wrist joint. The main control chip of the wireless communication device 8 for intelligent temperature control collects the heating power and real-time temperature of the wristband through the temperature sensing unit 6 and the heating electrode 7, and intelligently adjusts the heating power according to the preset temperature set by the user terminal 9 to...

Embodiment 2

[0044] Embodiment 2: Provide an intelligent flexible thermotherapy sheet based on cloud data control, which can be worn on movable joints or other parts, and is used for medical staff to professionally control patients' thermotherapy. The preparation process of the flexible electric heating element is similar to that of Example 1, and the amount of each raw material can be adjusted in equal proportions according to the specific size of the electric heating element. Different from Embodiment 1, the control board of the intelligent flexible thermotherapy sheet described in this embodiment uses a 4G network to publish the patient's thermotherapy status to the cloud server, and the medical staff set the hyperthermia parameters according to the specific conditions of the patient.

[0045] Furthermore, as a medical auxiliary device, the control board of the thermotherapy sheet in this embodiment has an expansion interface, and other types of sensors such as humidity (perspiration on ...

Abstract

The invention discloses a wearable electric heating element based on a wireless sensing technology and a preparing method of the wearable electric heating element. A flexible high-molecular material is adopted as a base body, an electric heating functional material is formed with a metal nanowire conductive transfusion network, the three-dimensional microscopic crease morphology of the nanometer scale is established on the conductive transfusion network, and the flexible electric heating element capable of stably working under the high-deformation conditions is obtained; in combination with the Internet-of-Things control technology, the wireless intelligent control over the flexible electric heating element is realized. The element is stable in heating, fits a human joint to deform, meanwhile does not limit the human motion function, precisely controls the temperature and has great application value in the field of wearable thermal therapy accessories.

Description

technical field [0001] The invention belongs to the technical field of intelligent wearable systems and flexible conductive materials, and in particular relates to a wearable electric heating element based on wireless sensing technology and a preparation method thereof. Background technique [0002] Hyperthermia is a common clinical auxiliary treatment in modern medicine. Medical research shows that appropriate warming can effectively improve blood circulation in the human body, relieve local congestion, and have very obvious effects on lumbar and cervical diseases. Most of the traditional hyperthermia devices have limitations such as short heating time, affecting human motor function, uncontrollable temperature, or poor portability. Therefore, the smart constant temperature flexible electric heating element that fits the deformation of human joints and is light and comfortable has important market value. [0003] Flexible electric heating elements are usually composed of f...
