Fabrication of zipping electrostatic actuators incorporating inkjet-printed layers

Herbert Shea, Samuel Rosset, Giulio Grasso

Zipping electrostatic actuators operate by bending flexible electrodes using electrostatic forces. This principle allows the use of a wide range of dielectric and conductive materials. Additive Manufacturing (AM) techniques can be used to fabricate these a ...

Sharp High-Aspect-Ratio AFM Tips Fabricated by a Combination of Deep Reactive Ion Etching and Focused Ion Beam Techniques

Luis Guillermo Villanueva Torrijo

The shape and dimensions of an atomic force microscope tip are crucial factors to obtain high resolution images at the nanoscale. When measuring samples with narrow trenches, inclined sidewalls near 90 or nanoscaled structures, standard silicon atomic forc ...

Micromachined tunable devices based on silicon integrated BaxSr1-xTiO3 thin films

Andreas Nöth

Thin Film Bulk Acoustic Wave Resonators (TFBARs) had been developed a decade ago and since then were implemented extensively in mobile communications devices. The "heart" of a TFBAR consists of a piezoelectric film that operates as an acousto-electric tran ...

Microfabricated electrically conducting and wear-resistant nanoprobes for scanning probe applications

Johannes Steen

The era of scanning probe microscopy (SPM) started twenty years ago. A cut gold cantilever with a glued diamond stylus served as the scanning probe. Within a few years the crystalline silicon (Si) became the – up to today – predominant SPM probe material. ...

Novel full platinum nanoprobes suitable for biological SPM experiments

Jürgen Brugger, Johannes Steen

We have developed a hybrid scanning probe microscopy sensor consisting of a SU-8 body and full platinum cantilever and tip. The fabrication process is based on surface-micromachining of a silicon wafer, where oxidation sharpened moulds define the tip shape ...

Surface micromachining of Ceramic-MEMS based on SU-8 micromoulding of Polyureasilazane

Jürgen Brugger, Vahid Fakhfouri

Chemical inertness and corrosion resistance make ceramic materials appropriate for Micro Electro-Mechanical Systems (MEMS) when aiming for sensing applications at high temperature or in harsh environment. Besides the usual fabrication techniques, such as p ...

Surface Micromachining of Polyureasilazane Based Ceramic-MEMS using SU-8 Micromolds

Jürgen Brugger, Vahid Fakhfouri, Sébastien Jiguet

We describe a novel surface micromachining process for the fabrication of ceramic-type MEMS devices, such as free-standing cantilevers, that is based on the use of high-aspect ratio micromolds of SU8 and aluminum as sacrificial layer. 250μm-high and 100-10 ...
