With the emergence of Apple's Apple Watch and various smart bracelets, the development of wearable devices has received increasing attention. Not long ago, a very futuristic video was widely circulated on the Internet: a person using a smart bracelet with a built-in projector to turn the skin of the forearm into a mobile phone touch screen, which can achieve a series of functions such as page turning and zooming. Experts from all sides have heated discussions on what is a wearable device, what is the use, and what bottlenecks exist in the current development.
In the theme area of ​​wearable devices and smart hardware, the booth site has both blood pressure measuring devices and positioning watches that prevent children from losing. The staff said that this watch has a built-in free SIM card for parents. Parents only need to download an APP on their mobile phone to use it. This watch has high positioning accuracy. As long as there is a mobile phone signal, the positioning signal will not be lost even indoors. . The child can also send and receive voice messages via the buttons on the watch.
Lin Wei, chairman of the Wearable Devices Committee, gave a speech on the theme of “Intelligent Hardware Ecology in the Post-Apple Watch Eraâ€. He first defined intelligent hardware: smart hardware is a technological concept following the smart phone, through the combination of software and hardware. Transform traditional equipment to have intelligent functions. After the intelligentization, the hardware has the ability to connect, realize the loading of Internet services, form a typical structure of “cloud+endâ€, and have added value such as big data. Smart hardware can be either electronic or traditional, such as water cups, even women's underwear, door locks, and automobiles. Lin Wei said that smart hardware is just a transitional statement like wearables. All future hardware is smart hardware. He said that although the industry has had various spit and ridicules for wearable devices and smart bracelets after the release of AppleWatch, overall, the wearable market has just started, there is a lot of room for growth, and wearable devices are not smart phones. And the application scenarios are different and cannot be eaten.
Dr. Li Huifang, terminal research and development center of China Telecom Guangzhou Research Institute, said that poor endurance performance is one of the bottlenecks faced by wearable devices. Due to the miniaturization of wearable devices, the battery size is also very small, and the battery capacity is unlikely to be large. At present, it is difficult to make a big breakthrough in battery technology, so wireless charging and fast charging technology can only be used as an alternative solution. However, both of these methods have problems of shortening battery life and causing the terminal to heat up quickly. Developing a lower power chip is an important direction to solve this bottleneck.
Jiang Tianjiao, assistant to the president of the doctor-seeking drug network, believes that wearable devices have great potential for development, but wearable devices are currently facing some problems. He said that there were very few people wearing smart watches and bracelets in the forum, and no one was wearing a mobile sphygmomanometer. He asked three questions on the spot: what can be measured by wearable devices, which devices are wearable, and which health data has the medical value of big data analysis. He said that currently wearable devices can monitor health indicators such as exercise, posture, body temperature, weight, heart rate, as well as chronic diseases such as ECG, blood pressure, blood sugar and blood oxygen. However, at present, there are problems in the monitoring indicators for chronic diseases that the detection values ​​are not accurate enough. Jiang Tianjiao stressed that he is not looking at wearable devices, but that there is a lack of development in wearable devices. He believes that lack of service is an important issue in the current development of wearable devices. Big data + service is an important direction for the future development of smart wearables.
