The Integration of Optical Stimulation in a Mechanically Dynamic Cell Culture Substrate

Herbert Shea, Matthias Imboden, Olexandr Gudozhnik

A cell culture well with integrated mechanical and optical stimulation is presented. This is achieved by combining dielectric elastomer soft actuators, also known as artificial muscles, and a varifocal micro-electromechanical mirror that couples light from ...

High-speed mechano-active multielectrode array for investigating rapid stretch effects on cardiac tissue

Herbert Shea, Matthias Imboden, Samuel Rosset, Alexandre Poulin, Christian Dellenbach, Stephan Rohr, Etienne de Coulon

Systematic investigations of the effects of mechano-electric coupling (MEC) on cellular cardiac electrophysiology lack experimental systems suitable to subject tissues to in-vivo like strain patterns while simultaneously reporting changes in electrical act ...

Building a Casimir metrology platform with a commercial MEMS sensor

Matthias Imboden

The Casimir Effect is a physical manifestation of quantum fluctuations of the electromagnetic vacuum. When two metal plates are placed close together, typically much less than a micron, the long wavelength modes between them are frozen out, giving rise to ...

An autonomous untethered fast soft robotic insect driven by low-voltage dielectric elastomer actuators

Yves Perriard, Herbert Shea, Yoan René Cyrille Civet, Matthias Imboden, Xinru Ji, Vito Cacucciolo, Xiaobin Ji, Xinchang Liu

Insects are a constant source of inspiration for roboticists. Their compliant bodies allow them to squeeze through small openings and be highly resilient to impacts. However, making subgram autonomous soft robots untethered and capable of responding intell ...

A Large Range of Motion 3D MEMS Scanner With Five Degrees of Freedom

Matthias Imboden

Here, we discuss a novel, mixed mode 3D XYZ scanner built within a single foundry process. The device has a large range of motion in X, Y, and Z (14.1 mu m in X and Y and 97.9 mu m in Z) and can also rotate about two axes (7.4 degrees), making it a 5 degre ...

An ultra-fast mechanically active cell culture substrate

Herbert Shea, Alexandre Poulin, Cristina Martin Olmos, Matthias Imboden, Samuel Rosset, Francesca Sorba

We present a mechanically active cell culture substrate that produces complex strain patterns and generates extremely high strain rates. The transparent miniaturized cell stretcher is compatible with live cell microscopy and provides a very compact and por ...
