Design and Control of a Zero Voltage Switching MEMS DC-DC Power Converter

Ghandour S., Despesse G., Basrour S., CEA-LETI, FR

In this paper, we present the modelling, the design, and the control of a DC-DC voltage converter using a MEMS variable capacitor. We estimate, for a 12V-10V step-down converter, an efficiency of 88% and a [...]

Design and Fabrication of Electromechanical Tweezers based on CNT Ropes

RAslan A., Basrour S., Le Poche H., CEA-LETI,Minatec, FR

The aim of this work is to design and fabricate electromechanical tweezers based on CNT ropes. The electromechanical behaviour of such ropes has been studied. The average of Young’s modulus of the rope has been [...]

Sacrificial membranes for serial valving in microsystems

Allain M., Berthier J., Basrour S., Pouteau P., CEA/LETI/MINATEC, FR

Valving is essential to microflow circuits in microsystem technology. Many different types of valves have already been designed. Membranes of sacrificial materials have been studied for one shot valving; however, the new design proposed here, [...]

Comparison of Piezoelectric MEMS Mechanical Vibration Energy Scavengers

Marzencki M., Basrour S., Belgacem B., Muralt P., Colin M., Tima Laboratory, FR

This paper presents a design, modelling, fabrication and experimental test results of MEMS mechanical vibration energy scavenging devices for micro power generation. There is a growing need for such structures in the field of wireless [...]

Design, Modelling and Optimisation of Integrated Piezoelectric Micro Power Generators

Marzencki M., Basrour S., Charlot B., TIMA, FR

This paper presents a mechanical vibration energy scavenging solution for micro power generation. The transduction is performed using a novel resonant cantilever beam SOI structure with a piezoelectric film. Simulation and optimization of such a [...]

High Damping Electrostatic System For Vibration Energy Scavenging

Despesse G., Chaillout J.J., Dekkaki I., Jager T., Léger J.M., Vassilev A., Basrour S., Charlot B., CEA-LETI, FR

We report here global simulations and designs of mechanical structures able to recover power over a large spectrum below 100 Hz. Contrary to existing structures tuned on a particular frequency, we have investigated conversion structures [...]

Simulation and Characterization of High Q Microresonators Fabricated by UV – LIGA

Basrour S., Majjad H., Coudevylle J.R., Coudevylle J.R., de Labachèlerie M., CNRS, FR

This paper is devoted to a study on a new metallic microresonator realized by UV-LIGA technique. This device is excited electrostatically and takes advantage of the contour modes or Lamé-modes of the structure. Design methods [...]
