Overview
ABSTRACT
Electromechanical machines and actuators allow for either converting movement energy into electricity or performing mechanical actions from an electrical source. From fly-by-wire devices to microsystems, the multiple functionalities of the "all-electric" present various concepts and structures. Furthermore, the new "electroactive" materials offer new opportunities in sectors as varied as aeronautics or medicine. This article presents the basic concepts and technologies used in the field of electromechanical actuators.

INTRODUCTION
Whether it's a question of converting motion energy into electricity or, conversely, performing a mechanical action from an electrical source, electromechanical machines and actuators are an essential vector for technological development. From electric flight controls to micro-systems, the multiple functionalities of "all-electricity" are available in a wide variety of concepts and structures. What's more, the emergence of "electroactive" materials, endowed with unprecedented properties and functionalities, is a powerful incentive to envisage future challenges in sectors as varied as aeronautics and medicine.
This dossier provides an overview of the basic concepts and technologies used in electromechanical actuators.
The first part is devoted to an analysis of the elementary physical phenomena and processes likely to achieve the desired energy conversion
