Abstract
Certain examples of the disclosure concern an implantable sensor. The implantable sensor includes a sensor assembly configured to connect to a suture. The sensor assembly also includes a substrate and a resonant circuit coupled to the substrate. The resonant circuit is configured to electrically resonate at a resonant frequency when exposed to a first electromagnetic field and to emit a second remotely detectable electromagnetic field. The substrate is configured to deform in response to a tensile force applied by the suture and to change a resonant parameter of the resonant circuit in response to the deformation.
