microjoule
Millionth of joule
A microjoule is one millionth of a joule, the standard unit of energy in the International System of Units.
This tiny measurement appears in contexts where energy quantities are extremely small, such as laser pulses, electronic circuits, or cellular biology.
The sensor requires only a few microjoules to operate.
