Modelling and Sensors for Magnetically-Levitated Disc Drives

Juan Patricio Tomás Peralta Fierro

The development of new industrial applications has diverted the focus of research towards compacter and faster rotatory drives. These requirements push the classical ball-bearings of electric motors to the limits in terms of operational lifetime and fricti ...

Silicon Photonic MEMS Add-Drop Filter

Niels Quack, Alain Yuji Takabayashi, Hamed Sattari

We demonstrate a compact add-drop filter based on a MEMS ring resonator implemented in IMEC's iSiPP50G silicon photonics platform. The device exhibits a port extinction of 20 dB and a port isolation of > 50 dB, upon actuation range of 0 V to 27 V. ...

Control-Free Mechanical Oscillator Powered by Shape Memory Alloys

Yves Perriard, Paolo Germano, Thomas Guillaume Martinez, Sean Thomas

Shape Memory Alloy (SMA) based actuators have been commonly used in applications that require being compact and lightweight. In this paper, the inherent stiffness of a flexure-based linear guide is used to create a bias-spring SMA actuator which further re ...

Designing compliant mechanisms composed of shape memory alloy and actuated by induction heating

Yves Perriard, Paolo Germano, Thomas Guillaume Martinez, Adrien Jean-Michel Thabuis, Sean Thomas

Shape Memory Alloys (SMAs) are a type of smart materials that reacts mechanically to heat. Due to their complex behavior, they are often used in a simple geometry such as wires. This constrains the output displacement of the alloy to a simple linear contra ...
