    摘要: In an embodiment, a method of compensating for capacitance change in a piezoelectric element of a fluid ejection device includes sensing a current driving a piezoelectric element, determining from the current that capacitance of the piezoelectric element has changed, and altering a rise time of the current driving the piezoelectric element to compensate for the changed capacitance.

    摘要: A method of depositing nano-dots on a substrate includes forming a template on the base, the template defining nano-pores, at least partially filling the nano-pores with a pillar material to define nano-pillars, depositing a dot material on the nano-pillars to define nano-dots on the nano-pillars, and contact printing the substrate with the array of nano-dots.

    摘要: A ring-type heating resistor for a thermal fluid-ejection mechanism includes resistive segments and conductive segments. The resistive segments are rectangular in shape. The resistive segments are separated from one another. The conductive segments are interleaved in relation to the resistive segments such that each conductive segment electrically connects two of the resistive segments. The resistive segments and the conductive segments together form a pseudo-ring that approximates a true ring.
