Technology is continually undergoing a constituent development caused by the appearance of billions new interconnected “things” and their entrenchment in our daily lives. One of the underlying versatile technologies, namely wearables, is able to capture rich contextual information produced by such devices and use it to deliver a legitimately personalized experience. The main aim of this paper is to shed light on the history of wearable devices and provide a state-of-the-art review on the wearable market. Moreover, the paper provides an extensive and diverse classification of wearables, based on various factors, a discussion on wireless communication technologies, architectures, data processing aspects, and market status, as well as a variety of other actual information on wearable technology. Finally, the survey highlights the critical challenges and existing/future solutions.

由于数十亿个新的相互连接的“事物”的出现及其在我们日常生活中的根深蒂固，导致技术不断发展。基本的通用技术之一，即可穿戴设备，能够捕获由此类设备产生的丰富的上下文信息，并使用它来提供合法的个性化体验。本文的主要目的是阐明可穿戴设备的历史，并对可穿戴设备市场进行最新的回顾。此外，本文基于各种因素，对无线通信技术，体系结构，数据处理方面和市场状况以及各种其他有关可穿戴技术的实际信息进行了讨论，对可穿戴设备进行了广泛而多样的分类。最后，
