Heartbeats can now be measured without placing sensors on the body, thanks to a new way to measure heartbeats remotely, in real time, and under controlled conditions with as much accuracy as electrocardiographs.
The researchers say this will allow for the development of "casual sensing" -- taking measurements as people go about their daily activities, for instance, when they are going to bed or getting ready to start the day. Kind of like a Fitbit, except accurate
"Taking measurements with sensors on the body can be stressful and troublesome, because you have to stop what you're doing," says Hiroyuki Sakai, a researcher at Panasonic. "What we tried to make was something that would offer people a way to monitor their body in a casual and relaxed environment."
