This research aimed to determine the use of technological tools for the care of geriatric patients who remain at home in order to glimpse opportunities and challenges for new studies. A systematic review of the literature was carried out following the PRISMA-2020 guidelines, analyzing documents published between 2017 and 2024 in scientific databases. Two independent researchers carried out the search, selection and analysis of the information, finally considering 52 documents. Among the findings obtained are the application of technology in the personalization of domestic environments; intelligent systems that monitor activity and vital signs; motion sensors, cameras and geolocation systems to monitor the patient; robots and virtual assistants to provide companionship and medication reminders; augmented reality and virtual reality systems for exercise routines, cognitive stimulation and entertainment. The conclusions indicate that technology is used for both physical and mental health care. It is revealed that the integration of smart technologies in the care of the elderly is not only feasible, but essential to address the challenges facing this society. However, collaboration between researchers, technology developers and healthcare professionals is vital to create solutions that truly respond to the needs of the elderly. Future research should evaluate the effectiveness of these technologies in real-life situations. Importantly, governments and healthcare institutions must recognize the value of technology in caring for older adults and support its development and implementation. Investing in technology will not only benefit older adults, but will also relieve pressure on healthcare systems and community resources.
