It looks more like a band-aid than a watch.
Advances in wearable tech have been pretty impressive lately, but the device described in a new Nature study blows the competition out of the water. While the Apple Watch is now equipped with an FDA-approved EKG sensor and companies like Samsung are going out of their way to make smartwatches look like fashion statements, the device described in the paper, published Wednesday, puts both to shame. 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.
