Title:
MICRO MAGNETIC FLUID DRIVING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/007893
Kind Code:
A1
Abstract:
Disclosed in the present invention are a micro magnetic fluid driving apparatus and method. The micro magnetic fluid driving apparatus comprises: a fixed cavity; at least one group of electrodes, wherein inner side faces of each group of electrodes are arranged opposite each other and located on an inner surface of the fixed cavity; a fluid input port and a fluid output port, which are respectively arranged at two ends of the fixed cavity and are in communication with the fixed cavity; and a plurality of conductor leads, wherein one end of each conductor lead is connected to a driving power source, and the other end thereof is connected to an outer side face of an electrode. A voltage output by the driving power source changes periodically; in the first half period and the second half period of a voltage period, the amplitude of voltages output by the driving power source does not change, but the directions of the voltages are opposite; and in the first half period and the second half period of each voltage period, external magnetic fields are respectively applied in a first direction and a second direction, wherein the first direction is opposite to the second direction, and the external magnetic fields make the directions of ampere forces acting on a fluid the same.
