The Hackaday Prize has had a few medical devices make the semifinalist cut, and of course wearables are on the list. How about implantables? That’s what Bionic Yourself 2.0 (or B10N1C) is doing with an implantable microcontroller, battery, and sensor system.

The hardware in B10N1C includes a electromyography sensor for measuring muscle activity, an accelerometer, a vibration motor, RFID reader/writer, temperature sensor, and – get this – a LED bar graph that will shine a light through the skin. That’s something we’ve never seen before, and if you’re becoming a cyborg, it’s a nice feature to have.

As with anything you would implant in your body, safety is a prime consideration for Bionic.the Lithium battery can be overcharged (yes, through a wireless charging setup) to 10V without a risk of fire or explosion, can be hit with a hammer, and can even be punctured. The enclosure is medical grade silicone, the contacts are medical grade stainless steel, and there’s a humidity sensor inside that will radio a message saying its time to remove the device if the moisture level in the enclosure increases.

Because the device is implanted under the skin, being able to recharge and update the code without a physical connection is the name of the game. There’s a coil for wireless charging, and a lot of work is going into over the air firmware updating. It’s an astonishing project, and while most people probably won’t opt for a cyborg implant, it will look really cool.

The project featured in this post is a quarterfinalist in The Hackaday Prize.
