The jet break-off length control apparatus further comprises a control apparatus adapted to calculate a characteristic of the stream of drops of predetermined volumes and adapted to provide a break-off length calibration signal to the resistive heater apparatus wherein the break-off length calibration signal is determined at least by the characteristic of the stream of drops of predetermined volumes. Further apparatus is adapted to inductively charge at least one drop and to cause electric field deflection of charged drops.

Jet stimulation apparatus comprised of a plurality of thermomechanical or electromechanical transducer devices that transfer mechanical energy to the fluid are claimed.
