Piezo Direct has announced a mesh-based piezo atomizer designed for nebulising and vaping applications, combining laser-drilled micro-holes with a proprietary post-processing technology aimed at reducing metal debris generated during manufacturing.
The atomizer uses holes as small as 2.0 microns to transform liquid into an inhalable mist. Vibrating mesh atomizers are used in devices such as nebulisers, inhalers and vaping systems, where the mesh component directly interacts with the liquid before the resulting mist reaches the user.
According to Piezo Direct, conventional laser drilling can leave behind molten metal residues around the micro-holes. The process can create a raised lip around the hole, as well as micron- and sub-micron-sized metal particles. The company refers to this residual material as the “volcano”.
