Pressure mediated tunable elastomeric optofluidic devices

Demetri Psaltis, Wuzhou Song

We introduce a novel tuning mechanism based on pressure actuating force, which can enable a broad spectrum of tunable elastomeric optofluidic devices. Thanks to the flexibility of the Polydimethylsiloxane (PDMS) material, the local deformation inside PDMS ...

Robotique collective et auto-assemblage

Michael Bonani

We present a study of collective robotics by including a mechatronics point of view. In the field it is usually claimed that collective robots are simple and relatively cheap because they are produced in large quantities. Instead in our study we show that ...

Low voltage electrostatic 90° turning flap for reflective MEMS display

Nico de Rooij, Wilfried Noell, Fabio Jutzi, François Gueissaz

A low voltage electrostatically actuated 90° turning flap is modeled and fabricated. The application is a new kind reflective, low-power, MEMS-based display with high contrast and reflectance. The system consists of a poly-silicon flap fabricated onto a si ...

Optimal Design and Sensorless Position Control of a Piezoelectric Motor Integrated into a Mechatronic Cylinder Lock

Yves Perriard, Markus Flückiger

Electronic door lock cylinders need some sort of mechanical actuator to toggle the locking state between open and closed. The main requirements are high security standards, low power consumption, reasonable production costs, and facile integration of the a ...

Mechanically tuneable microoptical structure based on PDMS

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Victor Javier Cadarso Busto

A system of two solid microlenses with uncoupled optical properties is presented. This structure has been designed in order to have one lens as a reference, while the other one can be mechanically tuneable. The reference lens presents a diameter of 2 mu m ...
