Discussion and conclusion
Most research in WPM systems has focused on applications related to older adults (aged more than 60 years), as opposed to younger adults. A study by Bergmann and McGregor reported that 93% of patients in an elderly care facility accepted a proposed WPM system, because of its low invasiveness and its non-interference with their normal daily life activities [63]. However, Bergmann and McGregor’s overall quality of individual studies was relatively low, with small participant numbers, limited details of methodology and a restricted reporting of research processes [63].
In this paper, we reviewed 20 wearable monitoring systems by selecting papers published from 2015 to 2017 in order to evaluate their technological advancements and their employment of advanced sensors and data collection techniques. We studied the design concepts of wearable wireless WPM systems, identified key specifications and parameters such as sensors and signals, data processing, integration, signal quality and userengagement and user-interaction that require attention. In addition, we have highlighted the potential of deployment of such technologies in the clinical environment [54, 64].
