Abstract: Encapsulation packages for stent-deployable monitoring devices formed of resonator sensors and allowing for magnetic biasing elements that exhibit a targeted impact on the mechanical characteristics of a stent are provided. Encapsulation packages are formed of different types and include a longitudinal shield and curved end on profile for aligning the shield within the deployable stent, the shield having perforations such that a resonator can be positioned adjacent the perforations for allowing particulate within the stent to collect and be measured by the resonator during deployment.

Abstract: A resonator comprising a magnetoelastic body having a mass load portion and an active resonating portion can be used in implementations such as a security tag. The resonator includes a mass at the mass load portion of the magnetoelastic body. Displacement of the magnetoelastic body is configured to occur at both the mass load portion and the active resonating portion. A strain at the active resonating portion during displacement is configured to be greater than a strain at the mass load portion during displacement.
