The manufacturing of mesh plates for inhalation devices typically relies on laser drilling, a process that leaves behind molten metal residue and jagged rims around micro-holes. These loose particles pose a health risk if inhaled, and their presence can cause unpredictable flow rates or droplet size drift. Piezo Direct has introduced a proprietary post-processing technique that strips away this debris without compromising the integrity of the titanium mesh or the precision of the 2.0-micron holes.

According to CEO Li Hsu, the company prioritized the removal of these residues to prevent potential lung damage from detached metal shards. Beyond safety, the technology maintains a strict diameter tolerance of ±0.3 microns, which is essential for ensuring droplets remain within the 3.0 to 4.2-micron range required for deep respiratory delivery. The titanium-based components are designed to withstand aggressive drug formulations and high-frequency vibrations exceeding 100 kHz. These atomizers are currently available for medical, consumer, and industrial applications, with future development cycles already focused on achieving sub-1.5-micron hole sizes.
