In this study, we offer a critical, theoretical framework for exploring the dynamics of power related to the technological tracking, measuring, and managing of aging bodies at the heart of these imaginaries. Drawing on critical gerontology, feminist tech- noscience, sociology of the body, and socio-gerontechnology, we iden- tify three dimensions of power relations where the designs, operations, scripts, and materialities of technological innovation implicate asymmet- rical relationships of control and intervention: (1) aging bodies and the power of numbers, (2) aging spaces and the power of surveillance, and (3) age care economies and gendered power relations.
