Using magnets for surrounding-sensors
I just had this idea I thought would be nice to share:
Imagine a approximation sensor of some sort (I have not looked one up yet) attached to your finger (or wherever you think it is useful) connected with a small electro-magnet loosely attached to your finger with the implant.
In off-mode, the electromagnet would not generate any field but when the approximation sensor detects an object nearby (distance must be defined) it forces the electromagnet to generate a field which you then would be able to feel with your finger.
The energy-source for both the sensor and the electro-magnet could be realized in form of a mobile-phone battery or something.
Future application would of course be internal (implanted) energy source.
what'ya think?
Edit: I just realized that smartphones have these tiny sensors on the top so these may be of some help. They are like 4x4x4 mm or something.

@newbie: That sounds a lot like our Bottlenose device, actually, which also allows to use different types of sensors. Kevin Warwick's students have also done something similar.

It seems a bit silly to me. If you're going to have a device attached to your finger that is supposed to translate sensor readings into vibrations, then why not vibrate the skin directly using a vibration motor or something like that? That completely eliminates the need for the magnetic implant, which comes with obvious disadvantages compared to an external stimulator.

Wouldn't a coil be far flatter? You could stick it in a glove.

Okay, despite the size and form I had in mind it's exactly like Grindhouse's bottlenose.. It seems I wasn't the frist one with that idea.. :)
