Temporary tattoos could make electronic telepathy and telekinesis possible

Temporary electronic tattoos could soon help people fly drones with only thought and talk seemingly telepathically without speech over smartphones, researchers say. Electrical engineer Todd Coleman at the University of California at San Diego is devising noninvasive means of controlling machines via the mind, techniques virtually everyone might be able to use.

Commanding machines using the brain is no longer the stuff of science fiction. In recent years, brain implants have enabled people to control robotics using only their minds, raising the prospect that one day patients could overcome disabilities using bionic limbs or mechanical exoskeletons.

But brain implants are invasive technologies, probably of use only to people in medical need of them. Instead, Coleman and his team are developing wireless flexible electronics one can apply on the forehead just like temporary tattoos to read brain activity.

"We want something we can use in the coffee shop to have fun," Coleman says.

The devices are less than 100 microns thick, the average diameter of a human hair. They consist of circuitry embedded in a layer or rubbery polyester that allow them to stretch, bend and wrinkle. They are barely visible when placed on skin, making them easy to conceal from others.

The devices can detect electrical signals linked with brain waves, and incorporate solar cells for power and antennas that allow them to communicate wirelessly or receive energy. Other elements can be added as well, like thermal sensors to monitor skin temperature and light detectors to analyze blood oxygen levels.

Using the electronic tattoos, Coleman and his colleagues have found they can detect brain signals reflective of mental states, such as recognition of familiar images. One application they are now pursuing is monitoring premature babies to detect the onset of seizures that can lead to epilepsy or brain development problems. The devices are now being commercialized for use as consumer, digital health, medical device, and industrial and defense products by startup MC10 in Cambridge, Mass.

Swirly Gloves

I finished my Pieces of Eight Mitts! Looking through some of the diagrams and pictures made it seem a bit daunting at first, but the pattern is very well-written and methodical. I like how the designer warns that anyone who attempts these mitts should be comfortable with the idea of “smoothing out” uneven stitch counts. I know I certainly had to do that a couple times!

I used Patons Kroy Socks in Singin’ the Blues Stripes, which is almost as good as the Starry Night colours I envisioned when I first saw this pattern. I love the alternating blue and grey stripes, and I’m super happy that I was able to start each mitt in about the same spot in the stripe pattern.

Mods: twisted ribbing for the thumbs, slwyif for a clean top edge, added some short rows to the hand to make the fit better for my teeny wrists, flipped the second mitt inside out twice so I could do regular twisted ribbing on both thumbs.

All in all these were quicker than I thought, and just as entertaining as I expected. Thanks for looking!

I want to do this!
