The graphene temporary tattoo seen here is the thinnest epidermal electronic device ever and according to the University of Texas at Austin researchers who developed it, the device can take some medical measurements as accurately as bulky wearable sensors like EKG monitors. From IEEE Spectrum:
Graphene’s conformity to the skin might be what enables the high-quality measurements. Air gaps between the skin and the relatively large, rigid electrodes used in conventional medical devices degrade these instruments’ signal quality. Newer sensors that stick to the skin and stretch and wrinkle with it have fewer airgaps, but because they’re still a few micrometers thick, and use gold electrodes hundreds of nanometers thick, they can lose contact with the skin when it wrinkles. The graphene in the Texas researchers’ device is 0.3-nm thick. Most of the tattoo’s bulk comes from the 463-nm-thick polymer support.
The next step is to add an antenna to the design so that signals can be beamed off the device to a phone or computer, says (electrical engineer Deji) Akinwande.

Marginalized Native American communities throughout the United States could have better access to high-speed internet if the Federal Communications Commission (FCC) decides to allow tribes to use the Educational Broadband Services (EBS) spectrum for services like telemedicine, transmitting medical records electronically, or an online high school.
U.S. Federal Communications Commission Chairman Ajit Pai proposed a new rule to allow carriers to block robocalls. “The American people are fed up with illegal robocalls,” he said.
Kudos to those of us who have chosen a less wasteful third option to “paper or plastic” at the supermarket or club stores. Tote bags are reusable, but they can be a pain to tote around. Here’s an upgrade to that planet-saving measure. The Club Cart Lotus Trolley Bag is that rare tote you’ll want […]
Looking for a career in IT, gaming or software development? In the ever-changing world of the internet, versatility is your biggest asset. In other words, mastering Java might not cut it in an interview if you don’t know C#. However, there’s a bundle that covers the essentials in most any language. The Legendary Learn to […]
Getting a set of cookware that will outlast you is one of those signs you’ve truly grown up. It used to be easy to find durable materials that also cook well, but these days it can be hard to tell what’s quality and what brands are coasting by on a recognizable name. Well, there’s at […]
