microvolt

1 5.3
A very small electric voltage equal to one millionth of a volt
  • noun
  • /ˈmaɪkroʊvoʊlt/
  • Specialized
: microvolt
  • Automatic artifact rejection removed any epoch with an amplitude greater than ±75 microvolts.

Examples

  • They're millivolts rather than microvolts, so muscle Muscle potentials are order of magnitude bigger than neural potentials.

  • Special output structures have recently been fabricated with conversion efficiencies as high as 220 microvolts per electron and RMS noise levels of less than one electron per pixel.

  • This has units of microvolt, microvolt seconds.

  • The minimum sensitivity used to record was 20 microvolts.

    Academic text (1995)

  • Recording parameters were as follows: bandpass filtering: 30 to 500 Hz; time window: 20 milliseconds (msec); scale: 200 microvolts (V) per division.

    Academic text (2006)

  • The minimum sensitivity used to record was 20 microvolts.

  • Automatic artifact rejection removed any epoch with an amplitude greater than ±75 microvolts.

  • "Low-level signals can be one-half or one-quarter of a microvolt," Weisfeld says.

microvolts plural

Morphology

microvolt = volt (transparent) = micro + volt

The meaning is directly compositional: 'micro-' means one millionth and 'volt' is the base unit of electric potential.

Etymology

The word microvolt joins micro- ('small'), the same micro- you see in microscope, with volt, the unit named after the scientist Volta. So a microvolt is a very small volt, equal to one millionth of a volt.
