ABSTRACT
This article lists the design principles of sensors of physical or mechanical quantities. It solely presents the most commonly used devises such as, for instance sensors of torque, force , weight, pressure, proximity, displacement, temperature and gas. This list is thus not exhaustive. This article finishes by presenting the new generation of sensors and in particular the smart sensors which integrate an internal calculation devise, a signal conditioning system, a communication interface and chemical sensors.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
This article, which follows on from
[R 400]
, describes the principles involved in the construction of sensors for physical or mechanical quantities. This article is a new edition of the Capteurs article written by Jacques Toux, from which some extracts have been taken.
In all the following paragraphs, the diagrams are not restrictive; they represent only the most commonly used devices.
