There are a wide variety of products in the wearable device market. Gartner, the world's leading information technology research and consultancy, believes that the market mainly includes nine types of wearable devices: smart watches, head-mounted displays (HMD), wearable cameras, smart bracelets, smart clothing, heart rate chest straps, sports Watches, smart Bluetooth headsets and other wearable devices. The market acceptance and product maturity of various types of wearable devices vary. Overall, Gartner expects that wearables will quickly become popular in the next two to five years, from 232 million units in 2015 to 477 million units in 2020, and will generate $61.7 billion in profit opportunities. The top ten wearable technologies and functions from 2017 to 2018 are listed below: Biometric certification Thanks to the fingerprint authentication function of biometric authentication sensors in smart phones, biometric authentication has gradually become mainstream. Biometrics are expected to be more widely used in wearable devices because of the "close-fitting" nature of wearable devices and the ability to capture and generate more complex, reliable, and tamper-resistant biometrics. Another major use is biometric authentication for wearable devices to support action payments. We have a deep experience in fingerprint authentication for smartphones. Currently, biometric authentication for wearable devices such as Apple Watch and Samsung GearS2 can be used to purchase merchandise through a mobile payment preloaded mobile payment solution. In addition, Tencent Qkey bracelet also has a specific payment function. Gartner predicts that by 2020, more than 45% of sold smart watches will be mobile-free without a mobile phone. Mobile health monitoring Wearable health monitoring devices collect and monitor physiological indicators such as weight, blood pressure, blood sugar, heart rate, sleep, and skin electrical response, and then upload this data to mobile applications and cloud services for monitoring, analysis, and feedback. Depending on whether the wearable device has a medical certificate and a user agreement, the collected data can also be sent to a doctor for monitoring and improving patient care. This area of ​​technology will promote medical research, enable new telemedicine solutions, and improve medical care, which is of great importance to patients with chronic conditions. Mobile Health Monitoring and Biometric Wearables will bring new business revenue through consulting and personalized consulting services while reducing costs, making better use of medical resources and improving patient and patient relationships. Emerging markets have a strong and essential need for this technology because of the lack of medical resources in remote areas, which is a common problem that they urgently need to solve. Energy harvesting for energy boost Energy boost refers to the use of energy harvesting technology to obtain energy to enhance battery power and extend the life of the device after charging. Radio waves, temperature differences, solar energy, and mechanical vibrations can all be sources of energy harvesting. This technology can generate additional power to extend the battery life of wearable devices, reduce the cost of running the device and improve the user experience. One of the reasons people give up fitness equipment is that they always forget to charge. If the charging frequency can be extended from a few days to once a week, people's usage patterns will change. Smart coach Smart coaching is most relevant to wearable fitness devices. Gartner divides these devices into five sub-categories: bracelets, smart clothing, heart rate chest straps, sports watches, and other health monitors. A smart instructor is a feature of a wearable fitness device that collects multiple biometric authentication data and instantly sends fitness suggestions, feedback, and notifications to users via intelligent software and analysis tools. Users can use the coaching function to perform specific fitness tasks or training, and collect information about smart fitness tips to improve fitness benefits or prevent sports injuries. We believe this feature will further enhance the value proposition of current wearable fitness devices. Virtual Personal Assistant (VPA) Smart watches and bracelets have no screen or screen and control elements that are small in size, and this poses a challenge to the user interface. Virtual personal assistants can overcome this barrier and gradually push users to get intelligent advice through wearable devices in a highly contextualized manner, such as: access, guidance, schedule management, to-do transaction management, and message priority. Wearable sensing technology will develop and combine different biometric data information (eg, heart rate galvanic response) to enable user contextualization, ultimately enabling the virtual personal assistant to provide recommendations based on the user's emotional/emotional state. In addition, wearable devices will play a central role in providing more biometric data points to smartphones, even beyond the emotional sensing capabilities of smartphone facial recognition. This development prospect is critical to promoting the value proposition and advantages of smart watches and bracelets, and will ultimately increase their popularity. Embedded security Endless wearable devices bring users a new generation of devices and gradually enter the enterprise. Consumers and organizations have been worried about the security of smartphones and other devices that are now emerging on wearables. Security measures can be deployed in all levels of software and hardware, and embedded security security measures implemented from a hardware (chip) perspective will be widely adopted. Cooling Agent, is a general term for all the chemicals that can produce cooling effects and are not strong. The most common Cooling Agent is menthol (especially L-menthol), but it should not be used in large quantities due to its strong odor and strong irritation to the skin, mucous tissue, and eyes. Therefore, many scientists have synthesized and extracted a new generation of cooling agent.
