Title (EN) SELF-POWERED SENSORS MONITORING QUASI-STATIC STRUCTURAL RESPONSE
(FR) CAPTEURS AUTO-ALIMENTÉS SURVEILLANT UNE RÉPONSE STRUCTURELLE QUASI-STATIQUE
Abstract: front page image
(EN)A self-powered sensing system is provided for the monitoring of quasi-static structural responses. The sensing system is comprised of: an energy concentrator having a member configured to detect a variation of a physical stimuli and change shape in response to the variation of the physical stimuli, where the variation typically occurs at a frequency less than one Hertz; a transducer coupled the member of the energy concentrator and generates a voltage in response to the change in shape of the member; and an event logging circuit configured to receive the voltage from the transducer and log the voltage in a non-volatile memory. Physical stimuli may include temperature, pressure or an applied force.
(FR)L'invention concerne un système de détection auto-alimenté permettant de surveiller des réponses structurelles quasi-statiques. Le système de détection est composé : d'un concentrateur d'énergie comprenant un élément configuré pour détecter une variation de stimuli physique et changer de forme en réponse à la variation des stimuli physiques, la variation ayant typiquement lieu à une fréquence inférieure à un Hertz ; un transducteur couplé à l'élément du concentrateur d'énergie et qui génère une tension en réponse au changement de forme de l'élément ; et un circuit de journalisation d'événements configuré pour recevoir la tension en provenance du transducteur et journaliser la tension dans une mémoire non volatile. Des stimuli physiques peuvent inclure la température, la pression ou une force appliquée.
