A capacitive screen that could detect both conductive and non-conductive items (say, a gloved hand or stylus), but passively, unlike Atmel and others' active solutions (this has its own substantial shortcomings).
An alternative to this is placing the items on a non-conductive surface, such as a wood or glass table or desk.
All you'll need is a TV-B-Gone kit and a few items from your local hardware store: conductive thread, sewing supplies and standard soldering tools, and before you know it, you'll be able to turn off any television in the room.
The items to be protected should be insulated from the conductive shell, since the EMP field washing over the shield can still induce voltages in solid state circuit boards.
Items collect static charge when spare electrons (trapped by a lack of conductive outlet) are collected or "swept up" by a passing body.
It is, though, electrically conductive.
Indeed, many ceramics are quite conductive electrically.
But carbon nanotubes are also highly conductive.
The result is conductive hearing loss.
There were motion sensors and stacks of conductive fabric — literally, fabric woven with conductive material like wire.
There is one immediate use for conductive concrete.
