Electrostatic-mechanical driven liquid micrometering device

Abstract

An electrostatic mechanically actuated micro-metering device having an array of fluid chambers with orifices for ejecting fluid is designed, such that the pitch of the chamber array is independent from length and height dimensions of the actuating membrane that comprises a chamber wall, resulting in a higher resolution without requiring a substantially exponential increase in the applied voltage.

Description

technical field [0001] The present invention relates to a liquid micrometer, and more particularly to an improved structure for a liquid micrometer driven by an electrostatic machine having an array of liquid chambers with apertures for measuring liquids, It achieves a higher density of arrays of liquid chambers. Background technique [0002] Liquid micrometry is useful in many applications, especially when liquid dosing is critical for functional or economic reasons. For example, a certain ingredient on the production line requires accurate metering to achieve the desired product quality, or an imported material requires accurate metering to reduce costs. [0003] Ink micrometry in pulsed or drop-on-demand (DOD) inkjet printing devices is one such application. Inkjet printing technology has revolutionized the office and home printer market over the past two decades and is gaining popularity in industrial printing applications. Pulse inkjet printing is accomplished by eje...

Problems solved by technology

This orientation limits the density that is the critical dimension of the chamber array, so as the diaphragm width increases, the density decreases and reduces the resolution of the device
