Watches and spectacles were “wearable technology” long before the marketing maven who dreamed the term up was born. But now that some of these devices are fitted with gizmos which let their wearers monitor and record their lives down to the millisecond, many technologists are asking what else the data thus generated might be used for.

He thinks Apple Watches, Google Glasses and their kin might provide a solution to the problem of password inflation.

So they get written down, obviating the point of their complexity. One way around this is to use unique bodily characteristics, known as biometrics, to identify people. Fingerprints and iris scans, in particular, have been tried, but both require special equipment. Mr Hernandez’s work offers an alternative that does not: ballistocardiography.
