Nowadays, wearable devices for detecting biological or chemical markers have developed rapidly and become a hot research direction in the field of health monitoring. This wearable device not only solves the growing demand for personalized medical treatment, but also finds and treats related diseases in advance to the greatest extent. If you combine this technology with diapers Disposable diapers The combination of baby underwear will undoubtedly bring great convenience to parents. Is there enough technical support to meet this idea? Next, it makes a brief analysis based on the current situation of technology at home and abroad.
In recent years, scholars at home and abroad have used electrochemical detection technology more and more widely in the fields of medical treatment, food, new energy and so on, and are developing in the direction of portability, wearability and intelligence, integrating qualitative or quantitative detection targets with smart phones, smart watches, tablets and other devices. With the development of flexible materials and microfluidic technology, many new electrochemical sensors have been derived. Capture and analyze biological fluids, such as urine, sweat, saliva, tears, etc. These sensors realize convenient and efficient detection by connecting with the above intelligent terminal.
For example, Yao and others have built a wearable automatic power supply sweat monitoring system integrating micro supercapacitors. The system integrates the sensor array into the flexible substrate material, which can not only detect the above substances, but also realize automatic power supply; Zhao and others have found another way to use a simple wearable sensor to accurately measure sweat and sweat volume. By absorbing sweat from the skin, the gel expands and measures, and the sweat rate is continuously monitored by smart watches. Xu et al. Developed a fully integrated battery free flexible electrochemical label, which can be pasted on the wall of food or beverage containers for a long time to realize the on-site monitoring of the migration of toxic substances such as lead and cadmium from containers to food, and realize the wireless data transmission and wireless power supply of equipment through anodic dissolution voltammetry, NFC module and flexible electrode array.
With the development of science and technology, more and more wearable devices have made great progress, and gradually formed a complete system, which combines flexible stretchable electronic technology, electrochemical sensor, microfluidic control technology, intelligent terminal and data analysis and processing software. At the same time, we should also pay attention to some problems that need to be solved, such as the impact of non target pollution on the sensor surface, the fixation of sensitive substances on the sensor, especially the long-term guarantee of the size of sensor or electronic components will also affect the wearer's comfort, such as the security of detection data needs to be encrypted at the software or hardware level to ensure the user's privacy, etc.
According to the above analysis, it is certain that the realization of smart diapers, disposable diapers and baby underwear is completely possible. However, in the current environment, many problems are waiting for us to study and explore, but also to find better solutions.
