Small ozone generator fabricated from low-temperature co-fired ceramics

Purpose The purpose of this study is the design, fabrication and evaluation of a miniature ozone generator using the principle of electric discharge are presented. Design/methodology/approach The device was fabricated using a low-temperature co-fired ceramics (LTCC) technology, by which a multilayered ceramic structure with integrated electrodes, buried channels and cavities in micro and millimeter scales was realized. Findings The developed ozone generator with the dimensions of 63.6 × 41.8 × 1.3 mm produces approximately 1 vol. % of ozone in oxygen flow of 15 ml/min, at an applied voltage of 7 kV. Originality/value A miniature ozone generator, manufactured in LTCC technology, produces high amount of ozone and more than it is described in the available references or in datasheets of commercial devices of similar size.

Planar hydrodynamic traps and buried channels for bead and cell trapping and releasing

A new process for the fabrication of two superposed layers of microfluidic channels connected by vias is used to trap and release particles in a transparent chip. Parallel manipulation of beads is studied and the rules for cell trapping are defined.
