The concept of smart rings was recently of interest to investors, and many companies responded to investors' questions on interactive platforms. ① Tianjian shares: The company focuses on the health and medical field, with its own brand of smart rings called "RAPTGO," which has functions such as motion monitoring. Currently, it is sold online on the JD.com platform and also has offline dealer channels. However, as a new product, smart rings are still in the stage of market development. In addition, the company has also discussed customized development and gesture control functions with B2B clients, and will continue to develop new versions based on market demand. The company's smart ring products have been successfully put into production, but currently account for a small proportion of business revenue. ② Yian Technology: In the field of smart wearables, the company has jointly developed products with a foreign smart ring manufacturer that have been launched in the USA. ③ Xiamen Intretech Inc.: The company has unique advantages in product design, research and development, and manufacturing based on the UDM business model. The VR glasses and smart ring projects are mainly influenced by downstream customer market promotion plans and progress, and currently progress is relatively slow. ④ Cosonic Intelligent Technologies: The company has completed the development and trial production verification work for smart rings and will continue to pay attention to opportunities in this niche category, promoting cooperation with scaled customers.
