1. a unit of electrical potential equal to one millionth of a volt
Usage: technical

Examples

• The EEG machine detected brain activity in microvolts.
• The sensor measured electrical signals as small as 50 microvolts.
• Nerve impulses generate potentials of only a few microvolts.
• The amplifier boosted the microvolt signal to a readable level.
• Medical equipment must be sensitive enough to detect microvolt changes.
• The oscilloscope displayed voltage fluctuations in the microvolt range.
