They are also used in some types of air filters, for electrostatic collection of dust particles, in electret ion chambers for measuring ionizing radiation or radon and in Vibration Energy Harvesting.
22.
The effect of this equation can be seen in the case of an object with a " frozen in " polarization like a bar electret, the electric analogue to a bar magnet.
23.
An "'electret microphone "'is a type of electrostatic capacitor-based microphone, which eliminates the need for a polarizing power supply by using a permanently charged material.
24.
Due to their good performance and ease of manufacture, hence low cost, the vast majority of microphones made today are electret microphones; a semiconductor manufacturer estimates annual production at over one billion units.
25.
Condenser microphones have impedance converter ( current amplifier ) circuitry that requires powering; in addition, the capsule of any non-electret, non-RF condenser microphone requires a polarizing voltage to be applied.
26.
Unlike other condenser microphones, electret types require no polarizing voltage, but they normally contain an integrated preamplifier, which does require a small amount of power ( often incorrectly called polarizing power or bias ).
27.
Personal computer sound cards, such as Creative Labs'Sound Blaster line use a 3.5 mm phone connector as a mono microphone input, and deliver a 5 V polarizing voltage on the ring to power electret microphones.
28.
An " electret " is a stable dielectric material with a permanently embedded static electric charge ( which, due to the high polar molecules, and then allowing it to re-solidify in a powerful electrostatic field.
29.
Only the best electret microphones rival good DC-polarized units in terms of noise level and quality; electret microphones lend themselves to inexpensive mass-production, while inherently expensive non-electret condenser microphones are made to higher quality.
