Researchers at Tufts University are testing tooth-mounted RFID chips which sense and transmit data on what goes in your mouth. From the ABC News report:
The sensors looks like custom microchips stuck to the tooth. They are flexible, tiny squares – ranging from 4 mm by 4 mm to an even smaller size of about 2 mm by 2 mm – that are applied directly to human teeth. Each one has three active layers made of titanium and gold, with a middle layer of either silk fibers or water-based gels. In small-scale studies, four human volunteers wore sensors, which had silk as the middle “detector” layer, on their teeth and swished liquids around in their mouths to see if the sensors would function. The researchers were testing for sugar and for alcohol. The tiny squares successfully sent wireless signals to tablets and cell phone devices.
Not sure what the problem is that they are trying to solve, but interesting nonetheless.
Have you hear of alcohol inter-lock devices that can be installed on cars? These are designed to deter recidivist drink drivers from driving drunk - they have to test themselves on the alcohol interlock device in order for their car to unlock / start. This is perhaps a more reliable solution to that problem. It could certainly answer problems in the compliance space. Work place drug testing?

Sounds like a good idea - stops them driving any car (rather than just the interlocked one). The drug testing one feels a little big brother - but may be useful for those who volunteer as part of an addictions programme?
