How come? She's using an ultra-accurate sensor that can capture clinical data at a distance. True, this scenario is still a dream, but early results are encouraging. The super sensor can already monitor a person's heartbeat from a metre away―something of a bonus for the team at the University of Sussex in Brighton, who only set out to improve the accuracy of electrocardiograms.
