Review: Dawn Nafus (ed.), Quantified: Biosensing Technologies in Everyday Life

We have, in the 21st century, moved into a new series of fascinations with biosensing, where our autonomic systems or an autonomic ‘self’, largely out of bounds for our own knowledge and understanding before now, are available. ‘Autonomic’ refers to the nervous system of a physiological self, but the extent of our autonomic selves would not otherwise be knowable or known but through sensory tracking devices now available to us. Biosensing, biohacking, biometrics and biopower are all part of a contemporary movement of intimate and intensified measure and are terms that Dawn Nafus's collection Quantified: Biosensing Technologies in Everyday Life deals with. The book discusses questions of measurement and tracking with the use of sensory technology and methods. This review considers where this collection sits in the literature and theoretical debates.
