Additional sensory inputs in the face
I am wanting to find a way to make implantable infrared heat sensors that could detect how hot/cold an object you're looking at is and a sonar sensor that could measure how far away an object is. I was thinking they could send there inputs to magnets behind my ears for the sonar and in my hand for the infrared. Anyone know how I could go about making this and what components I would need?

As far as having the sensors on your face, I'd think a pair of glasses would be the way to go. The electromagnetic output could then go right back around your ear to stimulate the implanted magnet. There are some speech libraries already made for the Arduino that could probably tell you the temperature in actual words instead of needing to learn to interpret a vibration to know the temperature. With the implanted magnet, I think you would be the only one to hear it but it might get very annoying unless there was a way to turn the voices (or even just a vibrating noise) off like a button on the side of the glasses.
Work towards having the sensors implanted if that is what you really want but test and perfect everything with wearable devices first. Once you know your ideas work, then focus on miniaturizing everything and bioproofing them for an actual implant.
A tragus implant is sounding kind of interesting right now.

There should be enough information on this page to recreate it but if you dig back into the blog there was a day-by-day account of what I did. You can also ask me questions.
My avatar still shows V1.0 of the wearable IR temperature sensor.
@ightden, you are totally right about different software and hardware. Neil was going for something that could be worn 16 hours a day while I was making a proof of concept. He had a full camera, probably taking the average of a whole field, whereas an IR distance sensor just gets a single reading and sends it as serial data. I didn't even bother with a custom PCB, I just kept a whole Arduino Pro Mini intact and stuffed it in a tiny enclosure.
If I were going to do this over I would get rid of all the extras like optional output for servos, chattering relays and electromagnetic coils. I would buy or print a case that made it simple to change the battery. In other words it would be a single purpose device.
Given my poor hearing I might be a candidate for the Bone Bridge but it's not much for DIY design. In the realm of poor garage hackers, what have you seen for bone conduction?
At this point I think a project that integrated IR temp sensing with a bone conduction transducer would be pretty cool but mounting to the bone is still out of the possible realm for anyone outside of medicine.
Bone conduction transducers need more power than you get a from headphone outputs but a 20mA output at 5V from an Arduino might have enough juice.
Now, if you can convince your doctor you are deaf and afford the cost of surgery then most of what I said is moot.
skin over the sensor, if it is planted subdermally, is going to make
reading infared almost impossible by my own guess.
