Performance assessment of a small-size ocean wave energy harvester

Yongjie Sang, Bertrand Dubus

A lightweight electromechanical device is studied to harvest energy of ocean waves and supply electrical power to small-size ocean observation equipment such as sonobuoys. It is composed of a magnet fixed to the floating housing which follows the motion of the ocean surface and a moving coil…

3D Patterning of Si by Contact Etching With Nanoporous Metals

Stéphane Bastide, Encarnacion Torralba, Mathieu Halbwax, Sylvain Le Gall, Elias Mpogui, Christine Cachet-Vivier, Vincent Magnin, Joseph Harari, Dmitri Yarekha, Jean-Pierre Vilcot

Nanoporous gold and platinum electrodes are used to pattern n-type silicon by contact etching at the macroscopic scale. This type of electrode has the advantage of forming nanocontacts between silicon, the metal and the electrolyte as in classical metal assisted chemical etching while ensuring…
