Wearable smart devices "are a general term for devices that apply wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing, and shoes.

Generalized wearable smart devices include fully functional, large-sized devices that can achieve complete or partial functions without relying on smartphones, such as smartwatches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as smart bracelets and smart jewelry for physical sign monitoring. With the advancement of technology and the changing demands of users, the form and application hotspots of wearable smart devices are also constantly changing.

Wearable technology has always been highly regarded in the international computer academic and industrial circles, but due to its high cost and complex technology, many related devices are only in the conceptual field. With the development of mobile Internet, technological progress and the launch of high-performance low-power processing chips, some wearable devices have moved from conceptualization to commercialization. New wearable devices continue to spread, and many technology companies have begun to explore this new field in depth.
