What would you do to gain a sixth sense? Some of us would submit to a minor surgical procedure where a magnet is implanted under the skin. While this isn’t the first time magnet implants have been mentioned here on Hackaday, [The Thought Emporium] did a phenomenal job of gathering the scattered data from blogs, forum posts, and personal experimentation into a short video which can be seen after the break.
As [The Thought Emporium] explains in more eloquent detail, a magnet under the skin allows the implantee to gain a permanent sense of strong magnetic fields. Implantation in a fingertip is most common because nerve density is high and probing is possible. Ear implants are the next most useful because oscillating magnetic fields can be translated to sound.
For some, this is merely a parlor trick. Lifting paper clips and messing with a compass are great fun. Can magnet implants be more than whimsical baubles?
The device works by connecting two antennas to an enclosure that contains a speaker. The enclosure is intended to be worn on the back with a harness securing it in place and wrapping the arms around the wearer’s body. The antennas are incorporated into a pair of gloves. When the antennas pick up electromagnetic radiation, the speaker emits a low frequency sound waves. They vibrate the enclosure and the arms, which in turn vibrate the body, signaling to the wearer that he or she is in an electromagnetic field, also referred to as hertzian space. A good deal of detail about the project can be found on his blog, or if you prefer, download his thesis paper in(PDF).
Various cybernetic limb and organ replacements were recently featured in IEEE’s flash demo called The Bionic Body Shop, but we were most interested by the bionic eye and the cochlear implant (we already discussed the featured powered exoskeleton). These are notable for the fact that they are not merely high-tech prosthetic replacements strapped to or worn on the body, but implants that are housed within the body and work with flesh-and-blood sense organs on a much closer level than any preceding technology.
