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. WSJ27My17
