The increasing elderly population in Japan necessitates innovative solutions to ensure their safety and well-being, particularly in the context of natural disasters. Smart homes, equipped with various sensors, are increasingly seen as a crucial element in this effort. These sensors monitor vital signs, detect falls, and monitor environmental conditions such as temperature and humidity. Data collected by these sensors are transmitted to a central system and, in many cases, to a dedicated disaster preparedness app on the elderly person’s smartphone. However, the reliability of such systems is paramount. Sensor malfunctions can lead to delayed or inaccurate information, potentially jeopardizing the safety of elderly residents. A recent study conducted by the National Institute of Geriatrics and Gerontology revealed a concerning trend. The study investigated the frequency of sensor failures in smart homes across various prefectures. The results indicated that sensor malfunctions, including intermittent connectivity issues and complete sensor failure, occurred significantly more often than initially anticipated. The most common cause was identified as battery depletion due to infrequent replacement, followed by physical damage from accidental knocks or spills. Furthermore, the study highlighted a crucial issue: the lack of immediate alert systems informing caregivers or emergency services when sensor failures occur. Without such notification, the elderly individual may be left vulnerable, especially during emergencies. This problem underscores the need for advanced features in disaster preparedness apps. Currently, many applications simply display data from the various sensors. However, they lack crucial functionalities such as self-diagnostic tools to detect sensor malfunctions or automated alerts to pre-designated contacts in the event of a failure. Implementing robust error detection mechanisms and automated notification systems within the apps could drastically improve the reliability and effectiveness of these crucial safety networks. Furthermore, user-friendly interfaces and clear instructions on sensor maintenance could mitigate the risk of failures stemming from human error. The development of such improved apps represents a critical step in leveraging technology to protect the vulnerable elderly population in Japan.
