This heart-sensing device has no wires, requires no charging, and is so small that it can wrap around a rat’s heart.
Study co-author Kenjiro Fukuda, Ph.D., a research scientist at Japan’s RIKEN Center for Emergent Matter Science is quick to say that his device represents a big step forward for wearables. It looks more like a band-aid than a watch, and it’s thinner than a piece of cardboard.
