Contact microphone print that page


A contact microphone , otherwise known as a pickup or a piezo, is a form of microphone designed to sense audio vibrations through solid objects. Unlike normal air microphones, contact mics act as transducers which pick up vibrations and convert them into a voltage which can then be made

Ohmic contact print that page

An ohmic contact is a region on a semiconductor device that has been prepared so that the current-voltage (I-V) curve of the device is linear and symmetric. If the I-V characteristic is non-linear and asymmetric, the contact is not ohmic, but is a blocking or Schottky contact . Typical | 2011/5/13 14:54:59
