Those of you sickly fascinated past the Circadia subdermal implant, a phone sized device from Grindhouse Wetware that Tim Cannon had installed in his forearm two years ago, will be happy to learn the same group of biohackers has released a new offering — and it'southward but slightly less macabre than its predecessor. Not content to rest upon their laurels, the folks at Grindhouse Wetware have been using this holiday season to perfect the strange art of lodging irregularly shaped electronic devices beneath the skin. A calendar week ago at Dusseldorf Cyborg Fair, they released their latest abstraction, the Northstar V1.

On the surface the Northstar dimly resembles the Circadia — of which Time Cannon, the device'southward designer, said, "Our first paradigm, the Circadia, was and then crazy that I could only use myself as a guinea pig in good conscience." Obviously, the  new Northstar has a few more than takers, as several members of the Grindhouse squad volunteered to have the implant installed.

The size of a half-dollar, the Northstar V1 contains several LED lights that turn on when a magnet is passed in a higher place them, eerily illuminating the user'due south skin with an consequence that imitates the bioluminescence that some fish and insects possess. The original idea for the device came from tattoo recipients who wanted a way to backlight their torso art, and indeed, there is a long tradition of crossover between the biohacker and tattoo community.

It'due south a rare brood of human who wants oddly shaped flashing LED devices parked inside their arm, and the folks who frequent tattoo parlors seem to contain a rich assortment of just such people. However, every bit the country of the art progresses and these devices go smaller and less obtrusive, it's likely they volition exist coveted by a wider population. But before such a reality can come to pass, a much wider and more attractive panoply of use cases volition demand to emerge. (Caution: the video below contains graphic images.)

This is not to say possessing a small patch of glowing skin doesn't have a kind of appeal, just it's the entreatment that features largely at Halloween parties and rave gatherings. On the other hand, large segments of the population have been demonstrably willing to install electronic implants in their body if information technology provides some clear health advantage, the pacemaker being the all-time case.

The biohacker customs has not been blind to this, which is why the Grindhouse Wetware squad plans to include biometric functionality in their next version of the Northstar. This could include taking blood pressure or blood sugar levels and reporting information technology to the user via Bluetooth on their mobile phone.

With the globe's ever increasing number of diabetes sufferers, this would rocket the Northstar into a new category of demand. Even without FDA approval, information technology seems probable in that location volition be plenty of adventurous and/or desperate patients willing to receive the implant in social club to get a better handle on their disease — at which point the Northstar will no dubiousness attract the involvement of the medical industrial complex and enter into the fray of mainstream medical gadgetry.

In the meantime, those interested in backlighting their tattoos or just beingness on the forefront of a new revolution in biohacking have a fresh and exciting ways of achieving that end.
