A 10-gram Microflyer for Vision-based Indoor Navigation

Dario Floreano, Jean-Daniel Nicoud, Jean-Christophe Zufferey, Antoine Beyeler, Adam Klaptocz

We aim at developing ultralight autonomous microflyers capable of navigating within houses or small built environments. Our latest prototype is a fixed-wing aircraft weighing a mere 10 g, flying around 1.5 m/s and carrying the necessary electronics for air ...

Vision-based Altitude and Pitch Estimation for Ultra-light Indoor Aircraft

Dario Floreano, Jean-Christophe Zufferey, Claudio Mattiussi, Antoine Beyeler

Autonomous control of ultra-light indoor microflyers is a difficult and largely unsolved task because of the strong limitations on the kind of sensors that can be embedded. We propose a new approach for altitude control of a 10-gram microflyer, where altit ...

Scanning Probe with Tuning Fork Sensor, Microfabricated Silicon Cantilever and Conductive Tip for Microscopy at Cryogenic Temperature

Nico de Rooij, Terunobu Akiyama, Kaspar Suter

A quartz tuning-fork (TF)-based scanning probe is presented for local electrical transport measurements on quantum devices below the liquid 4He temperature. The TF is utilized to drive and sense the mechanical oscillation of an attached, microfabricated ca ...

Bio-inspired Indoor Microflyers

Dario Floreano, Jean-Christophe Zufferey

There are not yet fully autonomous flying robots capable of maneuvering in small cluttered environments as insects do. The substantial weight and energy constraints typically encountered in this kind of robotic applications preclude the use of powerful pro ...

Q-factor optimization of a tuning-fork/fiber sensor for shear-force detection

Majed Chergui, Andrea Callegari, Jinquan Liu

We present the results of an exptl. and theor. study on the optimum design of shear-force sensors, used in scanning probe microscopes. We have optimized a configuration consisting of a tuning-fork/fiber-tip assembly, achieving quality factors (Q) exceeding ...

Integrating optics and micro-mechanics in a single substrate: a step toward monolithic integration in fused silica

Yves Bellouard

We present a novel optical sensor concept that merges integrated optics and micro-mechanics in a monolithic substrate. This concept pushes microsystems integration and defines a new class of monolithic optical microsystems where only optical signals are pr ...

Piezoelectric acoustic sensors and ultrasonic transducers based on textured PZT thin films

Nicolas Ledermann

This work dealt with the establishment of a reproducible and industrially exploitable fabrication technology for piezoelectric MEMS based on PZT thin films. {100}-textured piezoelectric 1-4 μm thick films were found to be the most suited materials for MEMS ...
