The implantation of devices and prostheses is considerably rising in recent years.

Abstract
The implantation of devices and prostheses is considerably rising in recent years. When an implanted medical prosthesis is equipped with a local wireless sensor, an early-onset identification of possible infections could be achieved. This paper proposes a method to transform a metallic dental implant into an antenna integrating a temperature UHF RFID sensor. A sensorized add-on disk, fully embedded in the dental implant's crown, collects the external interrogating electromagnetic field and transforms the implant itself into a top-excited dipole. After simulations, a preliminary prototype of the resulting Cyber-Tooth is experimented with a near-filed interrogation by means of an on-cheek antenna. Results are promising for the establishment of a robust backscattering link, as a good margin in the link budget is achievable with further improvements in the tuning of the disk harvester.File | Dimensione | Formato | |
