You have chosen to sponsor your bid up to a maximum amount of .
I am looking for someone being able to build a very very small device (= "invisible") which uses bone conduction to play sound using the teeth or the bones inside the mouth!
The device must be as small as possible, must run at least 4 hours and must accept its input by Bluetooth! (If you know a better wireless technology talk to me!)
If you don't know what I am talking about you might be the wrong person for this job!
For your enjoyment:
If you read the above mentioned paper carefully you will find a commercial product which does a very similar task!
(But I don't think you're able to send sound from a computer to their ITM. Or is it possible? Then you're my hero and you're ready to receive the full amount!!!)
I do NOT have a problem if such a device already exists and you 'only' have to adapt it for my needs!!
