摘要： A system may include a controller configured to cause a capacitance probe to subject a material to a first electric signal having a first frequency and determine a first capacitance of the material at the first frequency. The controller is configured to cause the capacitance probe to subject the material to a second electric signal at a second frequency and determine a second capacitance of the material at the second frequency. The material includes at least a first constituent phase and a second constituent phase. The first constituent phase and the second constituent phase have substantially similar dielectric constants at the first frequency and substantially different dielectric constants at the second frequency. The controller is further configured to determine a porosity of the material based on the first capacitance and determine a relative phase composition of the first constituent phase and the second constituent phase based on the second capacitance.

摘要： Systems and methods for controlling supply of electrical energy from power source(s) through a plurality of electrical conductors 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 such that the potential difference waveform(s) have a magnitude that exceeds a threshold overpotential for the pairs of electrical conductors in the electrolyte solution whilst sums of an absolute value of a potential difference across a double layer associated with the first electrical conductor in a pair and an absolute value of a potential difference across a double layer associated with a second electrical conductor in the pair is maintained below the threshold overpotential. Some or all electrical conductor(s) can be coupled to the power source(s) using respective capacitor(s).

摘要： In a method for jetting a droplet of an electrically conductive fluid, a Lorentz force is generated in the electrically conductive fluid. The Lorentz force is directed into an actuation direction. The actuation direction is a direction opposite to the droplet ejection direction. A jetting device is provided for printing a droplet of an electrically conductive fluid.

摘要： An electrohydrodynamic printing system includes a nozzle that dispenses a printing fluid and a substrate support. The nozzle includes a conductive portion. A voltage source applies a voltage differential between the conductive portion of the nozzle and the substrate support. A controller is configured to provide a burst mode waveform to the voltage source such that a drop of the printing fluid is caused to form from the conductive nozzle and travel toward the substrate support.
