Wearable flexible sensor with photothermal effect and antibacterial function

Abstract

The wearable flexible sensor disclosed in the present invention is a new type of wearable sensor with acrylic fiber spandex interwoven fabric as the base material. After the surface of the base material is treated with specific raw materials, it is soaked in the aqueous solution of carbon nanotubes and the aqueous solution of silver nitrate respectively. , and reduce silver ions to simple silver. The acrylic spandex interwoven substrate exhibits excellent electrical conductivity and can be used to monitor the macroscopic (finger joints, wrist joints, elbow and knee joints) and microscopic movements (facial muscles, throat, etc.) of the human body. Vibration and eyeball rotation), and because the base material of this sensor is an ordinary warp and weft interwoven fabric, it can be assembled on the clothing that people wear daily to realize real-time monitoring of human daily life activities. There are a large number of carbon nanotubes and silver particles, which will have a photothermal effect and antibacterial function after being exposed to light.

Description

technical field [0001] The invention relates to a flexible wearable sensor, in particular to a wearable flexible sensor with photothermal effect and antibacterial function. Background technique [0002] With the development of society and the improvement of people's living standards, people pay more and more attention to their quality of life and health. They hope that they can monitor and view their health status at any time, and can transmit the monitoring data to mobile devices and guide doctors at any time, so that To make judgments and guidance on their own health status in a timely manner, and to put forward reasonable suggestions. Wearable flexible sensors are an emerging field that has attracted extensive attention of researchers, because of their flexibility, scalability, portability, and wearability, they have great potential for development and application. [0003] Wearable flexible sensors in the prior art have defects such as large size, small stretching range...

AI Technical Summary

Problems solved by technology

[0003] Wearable flexible sensors in the prior art have defects such as large size, small stretching range, poor stretching effect, and low output capacity, which cannot be better applied to flexible wearable devices, especially when the size and stretching performance requirements Higher daily wear clothing, as well as the field of medical sensing systems that require higher output capability and sensitivity; wearable flexible sensors are often used to monitor the macro (finger joints, wrist joints, elbow joints and knee joints) of the human body in real time. , the existing wearable flexible sensor has no auxiliary protection and treatment effect on the joints, and its function is relatively single; at the same time, due to the special usability of wearable devices, the wearable flexible sensor is often in an environment where bacteria are easy to breed, while the existing Wearable flexible sensors have no substantial antibacterial properties, and need to be washed after long-term use, which can easily affect the sensing effect
