Title
(EN) SELF-RESONATING WIRELESS SENSOR SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS DE CAPTEUR SANS FIL AUTO-RÉSONANT
Abstract
(EN)
A system and method of detecting changes in an environment of an open circuit resonator configured to generate a signal when wirelessly powered by an external oscillating magnetic field, wherein the signal varies as a function of one or more environmental factors associated with the environment about the open circuit resonator. A monitoring device receives the signal from the open circuit resonator, captures data representative of the signal, compares the captured data to data previously received from the sensor to determine changes in the data, and estimates, based on the changes in the data, changes in one or more of the environmental factors.

L'invention concerne un système et un procédé de détection de changements dans un environnement d'un résonateur à circuit ouvert conçu pour générer un signal lorsqu'il est alimenté sans fil par un champ magnétique oscillant externe, le signal variant en fonction d'un ou de plusieurs facteurs environnementaux associés à l'environnement autour du résonateur à circuit ouvert. Un dispositif de surveillance reçoit le signal du résonateur à circuit ouvert, capture des données représentant le signal, compare les données capturées à des données précédemment reçues du capteur afin de déterminer des changements dans les données, et estime, en fonction des changements dans les données, des changements dans un ou plusieurs facteurs parmi les facteurs environnementaux.
