Abstract

The invention relates to power engineering, energy-saving technology of nanomembranes, nanohydromechanics, nanobiomedicine and biomedicine, in the field of new energy and drinking water sources, hydrogen power engineering, and nanorobots. The essence of the invention consists in increasing the efficiency of a nanopump by using a surface acoustic wave (SAW) from a plurality of digital transducers (DT), each of which is used in autonomous mode for transporting and purifying liquid through nanocapillary openings and tubes, for regenerating (purifying) the nanochannels themselves, and for removing products of purification. The design of the SAW structure uses a plurality of (three or more) digital transducers (DT) as sources of surface acoustic waves (SAW), each of which operates in autonomous mode for transporting and purifying liquid through nanocapillary openings and tubes, for regenerating (purifying) the nanochannels themselves, and for removing products of purification.
