In recent years, with the continuous development of science and technology such as biology and communication, wearable devices have gradually entered our daily life. Not only smart bracelets, smart watches, smart glasses and other products are emerging, but also smart headphones, smart accessories, and even Many refreshing wearable devices such as smart shoes and smart T-shirts have also come out one after another. With the advancement of technology and changes in user needs, the types and applications of wearable smart devices are constantly being updated.
A smart wearable device is a device that is installed on people, animals and objects to process related information and data through perception and transmission. There are various smart wearable devices, mainly including wrist-supported watches and wristbands, foot-supported shoes, socks and other foot-wearing products, and head-supported glasses, helmets, headbands, and clothing , school bags, crutches, accessories, etc.
The rise of smart wearable devices can be traced back to 2012. Google integrated micro-projectors, cameras, sensors, storage transmission and control systems into one glasses frame, and took the lead in launching smart glasses, opening the door to the wearable device market. According to the data consulting firm IDC, the annual shipment of smart wearable devices worldwide reached more than 100 million units in 2016. However, due to the lack of core technology, insufficient functions, high price, and insufficient user dependence, the development of these wearable smart devices was once quiet, and most of them were concentrated in the fields of sports, fitness and health.
However, the rapid development of biomedicine in recent years has created a new opportunity for the development of smart wearable devices. Although wearable medical devices need to face severe challenges corresponding to the medical industry, due to my country’s large population base and difficulty in seeking medical treatment, China is gradually moving towards an aging society and the prevalence of chronic diseases such as cardiovascular disease and diabetes in China is gradually increasing. The demand for health monitoring is increasing day by day, so the development of medical wearables still has huge advantages.
As the core device of wearable devices, sensors have played an important role in the rapid development of wearable devices. Through sensors, we can obtain the information we want to know at any time, and master more timely and accurate biological status. According to the different needs of users, the sensors used by wearable devices and the information expressed are also different.
Biosensor is a detection instrument that is sensitive to biological substances and can convert its concentration into electrical signals. It can convert the picked-up physiological information of the human body, such as heart rate, sleep quality and blood nutrient level, into electrical signals and output them through data analysis and judgment. human health. For example, the well-known smart bracelets and smart watches that detect heartbeat and heart rate, at the same time, some more professional medical equipment such as smart blood pressure meters, blood glucose meters, etc. are also gradually entering the general consumer market.
It is worth noting that there are still some defects in wearable medical devices, such as lack of standardization of detection data, no security guarantee, inaccurate detection data, etc., which may affect the user experience and hinder the development of the medical wearable device industry.
In short, the development of sensor technology has promoted the rise of the wearable medical device market, but there are still many aspects that need to be strengthened in order for wearable devices to truly land in the medical field. It is believed that with the rapid development of bio-communication technology, wearable technology and the market will usher in an “explosive period”.
