Title
(EN) SHIELDING AND/OR ENHANCEMENT OF TEMPERATURE-SENSING RFID DEVICES
(FR) BLINDAGE ET/OU AMÉLIORATION DE DISPOSITIFS RFID À DÉTECTION DE TEMPÉRATURE
Abstract
(EN)
A temperature-sensing RFID device includes an RFID chip and an antenna electrically coupled thereto. The RFID chip includes a temperature sensor, while the antenna is adapted to receive energy from an RF field and produce a signal. A shielding structure and/or a thermally conductive or absorbent structure may be associated with the RFID chip. The shielding structure is oriented so as to be positioned between at least a portion of the RFID chip and an outside environment and configured to shield the temperature sensor from at least one environmental factor capable of affecting a temperature sensed by the temperature sensor of an article to which the RFID device is secured. The thermally conductive or absorbent structure is oriented so as to be positioned between at least a portion of the RFID chip and the article and configured to enhance thermal coupling between the temperature sensor and the article.

Un dispositif RFID à détection de température comprend une puce RFID et une antenne couplée électriquement à celle-ci. La puce RFID comprend un capteur de température, tandis que l'antenne est conçue pour recevoir de l'énergie d'un champ RF et produire un signal. Une structure de blindage et/ou une structure thermiquement conductrice ou absorbante peut être associée à la puce RFID. La structure de blindage est orientée de manière à être positionnée entre au moins une partie de la puce RFID et un environnement extérieur et conçue pour protéger le capteur de température d'au moins un facteur environnemental pouvant affecter une température détectée par le capteur de température d'un article auquel le dispositif RFID est fixé. La structure thermiquement conductrice ou absorbante est orientée de manière à être positionnée entre au moins une partie de la puce RFID et l'article et conçue pour améliorer le couplage thermique entre le capteur de température et l'article.
