Abstract
The invention refers to a method and capacitive sensor for counting aerosol nanoparticles in an electric way. Aerosol particles, onto which a fluid was applied in an earlier process by known methods, change the capacitance of the dielectric of the capacitor when entering its field, which causes an electric signal. The method provides for detection of aerosol particles in a wide scope of their presence in the air and is not specific for any shape or chemical composition of nanoparticles.
