Outline of Final Research Achievements

Non-planar micromachining utilizing photofabrication techniques was developed for realizing electrical and fluidic functionalization of tube for use in the human body. Protrusion metal structures were fabricated on concave surfaces of a ceramic substrate by making protrusion on the concave surfaces and subsequent electroplating of metal layers. Fluidic channels have been also fabricated on the concave surfaces. Electrodes and non-conductive layers were fabricated on a polymer tube with a diameter of 0.4 mm and perforated windows were made using laser ablation for connecting inside of the tube and outside of the tube. Polymer multilayer tubes with pleural electrodes located inside the wall were fabricated using vapor deposited polymer as wall material for realizing thin-walled soft structure.
