Design and Optimisation of a Vibrating Wing Insect-Size Air Vehicle with Lumped Parameter Models and Compliant Links

Marguerite de La Bigne, Mathieu Colin, Eric Cattan, Sofiane Ghenna, Marie Zwingelstein, Sébastien Grondel, Olivier Thomas

Abstract This article presents the design of a microfabricated bio-inspired flapping-wing Nnano Aaerial Vvehicle (NAV), driven by an electromagnetic system. Our approach is based on artificial wings composed of rigid bodies connected by compliant links, which optimise aerodynamic forces though…

A 250 MHz to 1.1 THz sub-mm wave on-wafer characterization of InP HEMT using a multiline Thru-Reflect-Line calibration kit

Rita Younes, Mohammed Samnouni, Sylvie Lepilliet, Guillaume Ducournau, Nicolas Wichmann, Sylvain Bollaert

Abstract In this paper, we report an on-wafer High-Electron-Mobility transistor characterization method over a large frequency band [250 MHz–1.1 THz]. The transistor’s coplanar accesses were optimized to enable high-frequency measurement of the devices up to 1.1 THz. The characterization method…

Do Micropower Sources Meet the Needs of the Internet of Things?

Grace Whang, Randy Chen, Jacky Yu, Christopher Choi, Patricia Mcneil, Jérémie Chaillou, Christophe Loyez, Christophe Lethien, Bruce Dunn

Abstract The rapid global adoption of the Internet of Things (IoT), combined with the ongoing trend toward device miniaturization, has marked the emergence of compact, connected technologies. However, as device dimensions continue to decrease, power sources remain a critical bottleneck. Micropower…

Strain Decoupling in Ge/Si via Selective Misfit-Network Etching.

Youcef A Bioud, Meriem Bouchilaoun, Waldemar Schreiber, Redouane Amrar, Gilles Patriarche, Ali Soltani, Stefan Janz

CMOS-compatible Ge/Si heterostructures enable high-performance electroabsorption modulators, photodetectors, photonic interconnects, and multijunction photovoltaics, yet their scalability is hindered by the 4.2% lattice and thermal mismatch that generates dense dislocations. Here, we report a…
