About Microvolts

The microvolt (µV) equals 10⁻⁶ V, the scale of bioelectric signals and precision sensor outputs. EEG electroencephalography records brain-wave amplitudes of 10-100 µV; a standard thermocouple junction generates 5-40 µV/°C depending on type; Wheatstone-bridge strain-gauge outputs under load are typically 1-100 µV/V excitation. Instrumentation amplifiers with sub-microvolt offset are used in ECG front-ends. 1 µV = 10⁻³ mV = 10³ nV.

About Femtovolts

The femtovolt (fV) equals 10⁻¹⁵ V, at the threshold of the most sensitive voltage amplifiers ever built. Cryogenic SQUID amplifiers for neutrino-mass experiments and dark-matter searches operate near 1 fV/√Hz noise levels; Josephson-voltage-standard arrays show thermal voltage noise of a few femtovolts at millikelvin temperatures. 1 fV = 10⁻00b3 pV = 10³ aV.
