Method, system, and device for supplying electrical energy through electrical conductors adjacent to electrolyte solution environments

摘要

Systems and methods for controlling supply of electrical energy from power source(s) through a plurality of electrical conductors (electrodes, 1111) adjacent to a common electrolyte solution are disclosed. The power source(s) are controlled to apply potential difference waveform(s) between pairs of electrical conductors formed from the plurality of electrical conductors. Thus the potential difference waveform(s) have a magnitude that exceeds a threshold overpotential for the pairs of electrodes in the electrolyte solution. Sums of an absolute value of a potential difference across a double layer associated with the first electrode in a pair and an absolute value of a potential difference across a double layer associated with a second electrode in the pair is maintained below the threshold over potential. Some or all electrical conductor(s) can be coupled to the power source(s) using respective capacitor(s) 1130, 1250. The method and system may be used in a device such as a print head (piezo, thermal, MEM and electrostatic) to control the ejection of electrolyte droplets from an electrolyte solution.
