Micronozzles

Micronozzles are tiny nozzles with dimensions in the micrometer range. They are used in various applications that require precise dispensing of fluids or gases. These miniature devices can be manufactured using microfabrication techniques, similar to those used for producing microelectronic components.

The primary function of a micronozzle is to control the flow rate and direction of a fluid. By precisely shaping the nozzle orifice and controlling the pressure, a very small and well-defined stream can be generated. This precision is crucial in fields such as inkjet printing, where micronozzles deposit ink droplets onto paper with high accuracy.

In medical applications, micronozzles are employed for drug delivery systems, enabling the controlled release of medication at specific sites within the body. They can also be found in microfluidic devices, which are used for lab-on-a-chip applications, allowing for the manipulation and analysis of tiny volumes of liquids.

Micronozzles can be constructed from various materials, including silicon, glass, polymers, and metals, depending on the specific requirements of the application. Their small size allows for integration into compact systems and enables high-density arrays for parallel processing or large-area coverage. The development of micronozzle technology continues to advance, leading to new possibilities in micro-scale engineering and scientific research.
