At Bell Labs in 1962, West and his colleague Gerhard Sessler patented the electret microphone, in which thin sheets of polymer film, metal-coated on one side, are given a permanent charge to serve as the membrane and bias of a condenser microphone that helps convert sound to electrical signals with high fidelity.

Of course you can record straight from the two built in studio-quality electret condenser microphones direct to .wav or .mp3 format with bitrates up to 320kbps.

Term coined in 1885 by Oliver Heaviside. An electret is the electrostatic equivalent of a permanent magnet.

Why I love Wordie, reason #817:
I was just about to leave a comment on this page, involving a lame pun on the coincidental similarity between the name "Oliver Heaviside" and the "Heaviside Layer" (from the musical Cats), but first I googled "Heaviside Layer", and discovered, to my shock and delight, that there actually is a Heaviside Layer. It's part of Earth's ionosphere, and it was named after our man Oliver. T.S. Eliot just borrowed the term to describe his mystical feline heaven.
Wikipedia also gives the following interesting information (without any citations to support it):

I vaguely remember being exposed to something called the Heaviside function in my applied mathematics class, lo these many years ago. IIRC it had the odd property of being either right or left continuous, but not totally continuous.
Had I known about the pink fingernails and granite furniture, obviously I would have paid much closer attention.
Add this page to my reasons for lurving Wordie with a mad passionate lurve.
