Abstract
A method for transferring a viscous substance includes the steps of providing a viscous substance having an adhesive characteristic which changes in correpondence to the polarity of a voltage applied thereto. The viscous substance had an adhesive characteristic when no voltage is applied thereto and its adhesiveness is reduced when a voltage is applied thereto. The method further includes the steps of disposing the viscous substance between first and second electrodes and applying a voltage between the first and second electrodes to thereby substantially attach the entirety of the viscous substance to one of the first and second electrodes.
