Abstract/Summary

A novel miniature (28mm × 38mm) shielded Faraday cup is described for quantifying picocoulomb charges on millimetre environmental objects, such as small insects or plants, droplets, dust particles or powders. The electrometer electronics is contained within the device, avoiding any transfer of low level signals to an external electrometer. It is calibrated using a voltage ramp – capacitor method, generating defined charge pulses without a reference electrometer. The device can fit within an acoustic levitator to provide non-contact, zero leakage suspension of small objects, measuring charge on their release. Convenience and simplicity of use open new environmental charge measurement opportunities.
