We have studied self-coordinated transportation systems using SU-8 microstructures in open microchannels and here present a stochastic model for the bacteria-driven microbarge that is designed to mimic the motion of this system with and without chemical gr ...
We have developed a method for X-ray phase contrast imaging, which is based on a grating interferometer. The technique is capable of recording the phase shift of hard X-rays travelling through a sample, which greatly enhances the contrast of low absorbing ...
A silicon stamp for nanoimprint lithography (NIL) was fabricated from the patterns defined by stencil lithography. Since stencil lithography has a capability of producing sub-micron patterns in a single process, we were able to make a silicon stamp with a ...
We propose a microfabrication technology for a flexible temperature sensor with a 100x100 mu m(2) sensing area and a probe length of 7 cm. We use a biocompatible new high temperature-resistant polyimide (U-Vamish-S, Ube, Dosseldorf, Germany) to embed a thi ...

We have discovered a micro/nanopatterning technique based on the patterning of a PDMS membrane/film, which involves bonding a PDMS structure/stamp (that has the desired patterns) to a PDMS film. The technique, which we call "bond-detach lithography", was d ...
Piezoelectric micro-electro-mechanical systems (MEMS) are finding an increased interest for applications requiring high frequency operation and high mechanical quality. The aim of this work was to improve piezoelectric MEMS along two main research directio ...
Scanning probe microscopy has become, nowadays, a branch of microscopy widely used to image surfaces of different specimens. Among the various applications, the magnetic imaging is one of the most exciting scanning probe microscopy techniques. It allows th ...
Diffraction gratings integrated with MEMS has many applications as they can offer shot noise limited sub-nm displacement detection sensitivities but are limited in range. A two-wavelength readout method is developed that maintains high sensitivity while in ...
The authors report on the achievement of optically pumped III-V nitride blue microdisk lasers operating at room temperature. Controlled wet chemical etching of an AlInN interlayer lattice matched to GaN allows forming inverted cone pedestals. Whispering ga ...
Increased intraocular pressure (IOP) is the leading cause and the hallmark of Glaucoma, an asymptomatic and irreversible degenerative disease that, undetected or untreated, progresses to blindness due to optic nerve atrophy. Glaucoma is the second cause of ...
