Fluidic micromixer made in LTCC technology - preliminary results

A specialized mixing structure incorporating LTCC (Low Temperature Cofired Ceramic) technology was designed and fabricated. Such structures can be applied in a wide range of chemical and biological microsystems. In order to achieve the best fluid mixing efficiency, few different geometries were tested and evaluated. Solutions of phenolphthalein and sodium hydroxide in ethyl alcohol were used in the performed experiments. A customized method of evaluation was proposed and successfully applied. In general, mixing performance varied with shape and dimensions of the mixing structure. The mixing channel technology, evaluation experiment as well as obtained results are presented in this article.
