2. Paperlike sheets with a lot to say
Researchers at Michigan /State and Georgia Tech
have developed a laminate very much like a sheet of paper that can
function as a loudspeaker. To demonstrate its powers, they sewed
segments of the stuff into a Michigan State Flag and used it to
play the school's fight song. The device can also function as a
microphone. It is so thin and light that you can fold it up or roll
it into a cylinder and it requires no external power to operate.
The device is known as a ferroelectret nanogenerator, or FENG and
it's made of several layers, including polypropylene and metal.
