Exemplary systems and method are directed to a sensing device, and to a pressure sensing system and method. An exemplary method includes supplying electromagnetic energy to a transducer which is configured to reflect the electromagnetic energy at a ring frequency determined by an inductance of the transducer, wherein the inductance changes in response to compression of the inductive element. The ring frequency of electromagnetic energy reflected by the transducer is correlated to a pressure value.

La présente invention concerne des exemples de systèmes et procédé qui s'appliquent à un dispositif de détection, et un système et procédé de détection de pression. Un exemple de procédé consiste à fournir de l'énergie électromagnétique à un capteur qui est configuré pour réfléchir l'énergie électromagnétique à une fréquence annulaire déterminée par une inductance du capteur, l'inductance changeant en réponse à une compression de l'élément inductif. La fréquence annulaire de l'énergie électromagnétique réfléchie par le capteur est corrélée à une valeur de pression.
