Abstract

Passive Radio Frequency Identification (RFID) implantable antennas experience low efficiency due to the capacitive loading of human tissue that the implantable design has to overcome. Here we present a passive UHF implantable device able to produce a read range of 65 cm (EU frequency band) and 80 cm (US frequency band) from within the body. With a slight adjustment, this self-sensing tag can be utilized to sense microbial growth within the body once mounted upon a voice prosthesis. Simulated Candida albicans biofilm growth can be detected within the body with this sensor from early and up to a mature biofilm thickness of 30 µm (0 to 48-hour growth in vitro equivalent); allowing for detection before any infection symptoms within a patient become apparent (as early as 4-hour biofilm colonization (5 µm thickness)) and before the voice prosthesis experiences failure. This passive UHF device would permit cost-effective immediate medical intervention before any serious consequence could occur to a voice prosthesis patient.
