PRINT ARRAY AND METHOD OF FLUID TRANSFER

摘要

A print array (240) that incorporates reservoir(s) (412), microchannels (422) and micropumps (434) such as electrohydrodynamic (EHD) pumps for selectively dispensing fluid from the reservoir(s) onto the surface of a receptor (250) is disclosed. The control signals for the pumps are implemented using electronic fluid modulation (EFM) to selectively dispense fluid from the reservoir(s) of the print array onto a receptor.
