This literature review examines the role of wearable technologies in healthcare, specifically focusing on their application within the scope of care domain. It begins by introducing wearable technologies like body sensors and head-mounted displays, highlighting their potential to improve health and well-being. The review addresses key questions, including the newest wearable technologies, their advantages and disadvantages, implementation costs, and steps for production and implementation. It categorizes wearable technologies into three types: monitoring individual bodies, enhancing senses, and replacing or enhancing bodily functions. The review explores the advantages of wearable technologies, such as a person-centered approach, remote patient monitoring, and data accuracy, while also addressing disadvantages like concerns about dependability, security, and data accuracy. It also examines the costs associated with implementation and the steps necessary for successful production and implementation, including physician acceptance, patient compliance, and security considerations. Finally, the review discusses the Unified Theory of Acceptance and Use of Technology (UTAUT) as a framework supporting the adoption of wearable technologies in healthcare.
