People decrease their activities and social interaction in their aging stages. Wearable technology (WT) is one of the emerging technologies that help to sustain the quality of life (QOL) through monitoring and encouragement. To date, only limited research has been done regarding older peoples’ adoption of WT. The review shows a clear gap, especially for older people over 65, which have the fastest decrease and need the most attention to sustain their QOL. Therefore, this study examines how older people over 65 can maintain their QOL through the adoption of WT. Older people will have a prolonged QOL, which will also benefit their families. Governments, hospitals and practitioners will have reduced workload due to a slowing of the natural aging process. Implementing technologies, such as the Internet of Things (IoT), enhances health automatisation, while new monitoring devices increase accuracy and reaction time. Some barriers need to be mitigated to increase WT acceptance.
