Aging is inevitable; faced with the global aging population, how to make good use of cross-disciplinary technological integration for enhancing the care of the elderly in the physical, psychological and social environments becomes a very important issue. This is called the Gerontechnology. For the general public, “aging” often refers to the physiologically aging body parts. However, aging actually has psychological and social dimensions. From the analysis of the age groups, the proportion of the young population (0–14 years old) is decreasing year by year due to the declining birth rate. Currently, the young population only accounts for 13.45% of the total population. In Taiwan, the population over 65 years old accounts for 12.83% of the total population, making Taiwan approach the Aged Society, in which the elderly account for 14% of the total population. What is the Gerontechnology? Gerontechnology is actually a compound word that has been created to meet the needs of social development and is formed by combining Gerontology with Technology. Herman Bouma, a pioneer scholar in the Gerontechnology field, proposed to “understand technology and aging, and ensure the best technological environment so that we can support the elderly”. By definition, this is an application of technology that integrates different disciplines. It requires not only the participation of biomedical scholars and engineering scholars but also the involvement of scholars in social sciences, humanities, planning and design in order to create gerontechnological products characterized by both practical and industrial benefits. Currently, there are a number of operating service modes and a variety of home care application products on the market, such as the concept design of intelligent medicine cans, fall detectors, psychological comfort mechanical seals, indoor and outdoor universal lightweight electric vehicles. We should integrate this concept of technology into our daily lives, not allow technology to cause distress or fear, and enable technology to create comfort and security, thus generating the feeling of mutual trust. In addition, it can reduce the social cost of care for the elderly and shorten the time and distance between the elderly and their children, relatives and friends to enhance their interaction and emotional exchanges.
