Ageing is not only a chronological matter. The following contributions at the crossroad of STS, material gerontology, design, and medical sociology offer alternative views on ageing and care. Ageing emerges as a boundary object through which authors explore the relationship with technologies and technology-based processes and practices. Authors point out that becoming older is a sociomaterial process and emphasize the importance of thinking with care when designing technology as well as the relevance of the socio-technical imaginary in conceptualizing older people.
