A Contribution on Some Basic Definitions of Sensors Properties

This paper describes, through simple examples, the meaning of some key terms frequently used, sometimes incorrectly, in the field of sensors. They are sensor response curve, sensitivity, noise, drift, resolution, and selectivity. These words, if well-interpreted, represent a powerful vehicle of information and may symbolize part of a common knowledge useful for a sound dissemination of results relative to the sensors research. All of this is also aimed at stimulating any effort in order to facilitate the transition between sensor and sensor science development.
