Continuing efforts to more seamlessly integrate biosensors with our bodies, Princeton University researchers developed a temporary tattoo-like platform for "epidermal electronics." Nanoengineer Michael McAlpine and his colleagues published their work in last week's issue of the journal Science
. From Science News:
The electronic components — which can include light-emitting diodes, solar cells, transistors and antennae, among other things — were all constructed in a malleable net of wavy S-shapes similar to old-fashioned coiled telephone cords, which allows the circuits to work when stretched in any direction.
The researchers sandwiched these components between two protective layers of polyimide, a type of polymer. These layers sit on top of a rubbery silicone film that adheres to skin with weak chemical bonds. The device can also be applied in a temporary tattoo, which both disguises the grid and makes it stick longer.
Rogers is focused on medical applications for the electronic skin. But the basic building blocks of the system can be configured in many ways for widely different uses, he says.
“I think creative folks out there will think of things we haven’t even contemplated,” Rogers says.
For example, the technology has drawn the interest of security-minded people who might be interested in using the electronics to develop a covert communication system. “CIA and others have been interested,” Rogers says. A tiny hidden patch of electronics on the throat, for instance, could allow two agents to covertly communicate with one another. The electronics could detect and transmit muscle activity that represents words, all without the person making a sound.

The Cobham catalog, exposed by The Intercept, features countless pages of surveillance gadgets sold to U.S. police to spy on American citizens: tiny black boxes with a big interest in you. In the creepily bland feature lists and nerdy product names is a whisper of a dark future; perhaps darker than anyone can imagine.
This image depicts the most commonly-found stylesheet colors on the web’s top sites—Paul Hebert did an amazing amount of analysis and this is just one of the intriguing visualizations he came up with. Most of these are obvious staples, especially HTML red and blue, though it’s interesting how far the blue “cluster” is from the […]
With the cacophony of an election year ablaze with unparalleled drama being fought on the front lines of Twitter, we find ourselves slowing down and staring at it like a bad accident. The need for escapist relief is perhaps more dire than usual right now. This fall, if it’s drama you crave, but the Hillary […]
TV antennas are making a comeback, and the Ghost Indoor HDTV antenna is a great example of why. Unlike the old bunny ear-style antennas, this compact antenna is barely noticeable and picks up channels easily. Plus with the addition of streaming services like Netflix, we find ourselves with plenty to watch without a pricey monthly cable bill. The Ghost […]
I’ve never really felt the need to purchase a smartwatch because a lot of them aren’t very functional, but at just shy of $30, the Martian Notifier Smartwatch was worth checking out. For that low of a price, it actually does feature an impressive amount of functionality, and comes in handy when you don’t want to be carrying around your […]
