An implanted antenna system for the monitoring of bioresorbability of a biocompatible scaffold embedded into a bone fracture

Abstract

In this paper the dielectric properties of an implanted bioresorbable scaffold that is being used for the acceleration of the healing process of a fractured bone have been investigated. An implanted antenna system is presented for the monitoring of the s21 resorption rate of the scaffold, which gives an indication on the healing process of the bone fracture. A simulation model of a three layer body phantom was used for the evaluation of the response of the system as the introduced fracture gradually healed, turning from blood to bone marrow and bone cortical in five steps.
