Wearable flexible sensor with photothermal effect and antibacterial function

Abstract

The invention discloses a wearable flexible sensor which is a novel wearable sensor taking an acrylon-spandex interwoven fabric as a base material. After the surface of the base material is treated byusing a specific raw material, the base material is soaked in a carbon nanotube aqueous solution and a silver nitrate aqueous solution in sequence, and silver ions are reduced into elemental silver.The acrylon-spandex interwoven base material shows excellent conductivity, so that the sensor can be used for monitoring macroscopic (finger joints, wrist joints, elbow joints and knee joints) and microscopic motion (facial muscle, throat vibration and eyeball rotation) of a human body. The base material of the sensor is a common warp and weft interwoven woven fabric, and the sensor can be completely assembled on clothes worn by people in daily life to achieve real-time monitoring of daily life activities of the human body. Meanwhile, due to the fact that a large number of carbon nano tubes and silver particles are attached to the surface of the base material of the sensor, a photothermal effect can be generated after illumination, and an antibacterial function is achieved.

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 are more and more concerned about their quality of life and health, hoping to monitor and view their health at any time, and can transmit monitoring data to mobile devices and instruct doctors at any time. Make judgments and guidance on their own health conditions in a timely manner, and put forward reasonable suggestions. Wearable flexible sensors are an emerging field that has attracted wide attention from researchers. It has the advantages of flexibility, scalability, portability, and wearability, and has huge development and application potential. [0003] The wearable flexible sensor in the prior art has defects such as large size, small stretching range, poor stretching effect, and low ou...

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
