Gerontechnology, also called gerotechnology, is an inter- and multidisciplinary academic and professional field combining gerontology and technology. Sustainability of an aging society depends upon our effectiveness in creating technological environments, including assistive technology and inclusive design, for innovative and independent living and social participation of older adults in any state of health, comfort and safety. In short, gerontechnology concerns matching technological environments to health, housing, mobility, communication, leisure and work of older people. Gerontechnology is most frequently identified as a subset of HealthTech and is more commonly referred to as AgeTech in Europe and the United States. Research outcomes form the basis for designers, builders, engineers, manufacturers, and those in the health professions (nursing, medicine, gerontology, geriatrics, environmental psychology, developmental psychology, etc.), to provide an optimum living environment for the widest range of ages. Gerontechnology is considered an adjunct to the promotion of human health and well-being. It pertains to both human development and aging with the aim to compress morbidity and to increase vitality and quality of life throughout the lifespan. It creates solutions to extend the working phase in society by maximizing the vital and productive years in the later years of life, which consequently reduces the cost of care. The overall framework of gerontechnology may be seen as a matrix of domains of human activity: (1) health & self-esteem, housing & activities of daily living, communication & governance, mobility & transport, work & leisure, as well as (2) technology interventions or impact levels (enhancement & satisfaction, prevention & engagement, compensation & assistance, care and care organisation). Underpinning all these elements are generic and applied evidence-based research. Such research supports the development of products and services.
