  • Encapsulation Approaches for In-Stent Wireless Magnetoelastic Sensors

    Wireless magnetoelastic sensors are capable of measuring biomass accumulation within stents. One major challenge for these sensors is designing suitable encapsulation that protects the sensor during rigorous minimally-invasive deployment while also retaining its ability to sense the biomass. This paper describes two polymer-based package designs that meet these requirements using different compromises for the mechanical stiffness of the stent; both a flexible and a stiff encapsulation design allow the sensors to survive bending with a radius of curvature as small as 3 cm. In situ tests performed on the flexible design show a wireless range of ≈10 cm.
