Configuration of control system for damage tolerance of a tensegrity bridge

Ian Smith, Nizar Bel Hadj Ali, Sinan Korkmaz

Tensegrity structures are spatial, discrete, and lightweight structures that are composed of struts in compression and pre-stressed cables. Stability is provided by the self-stress state between elements independently of external actions. Tensegrity struct ...

Dielectric Elastomer Actuators for Microfluidics

Herbert Shea, Samuel Rosset, Luc Maffli

One of the goals of microfluidics is to bring a whole laboratory processing chain on a few square centimeters, Lab-On-Chips (LOC). But current LOCs require many heavy and power-consuming off-chip controls like pneumatics, pumps and valves, which keep the s ...

Design, Optimization, and Sensorless Control of a Linear Actuator

Joël Maridor

Electrical contactors are relays for interputing high currents (up to 2000 A). They consist of three main distinct parts: the low voltage circuit, the high voltage circuit and the linear actuator that moves the contact. The purpose of this thesis is to des ...
