Abstract
This letter demonstrates, for the first time, a biocompatible radio frequency identification (RFID) tag fabricated on an Ormocer substrate and encapsulated in it. Ormocomp belongs to a group of hybrid organic-inorganic photostructurable materials called Ormocers. It is biocompatible, chemically inert, and electrically insulating-ideal for body-implantable applications. In this letter, we have developed an Ormocomp-based printed circuit board and packaging method and implemented a biocompatible RFID tag.
Highlights
Since the first implantable pacemaker in 1958, numerous implantable devices have been developed to address various physiological, biochemical, or physical needs for medication, caring, and monitoring [1]–[3]
One common challenge in developing implantable devices is the biocompatibility of materials that are exposed to body tissues [2]
As a proof of concept, in this letter, we describe the fabrication process of an Ormocomp-based electronic product code (EPC) ultra high frequency (UHF) Gen2 radio frequency identification (RFID) tag containing a control integrated circuits (ICs) and a loop antenna
Summary
Since the first implantable pacemaker in 1958, numerous implantable devices have been developed to address various physiological, biochemical, or physical needs for medication, caring, and monitoring [1]–[3]. Due to the diverse functions and specifications of these implantable devices, different materials, structures, and electronics have to be applied and designed. One common challenge in developing implantable devices is the biocompatibility of materials that are exposed to body tissues [2]. Implanted devices are either encased with biocompatible materials or covered with biocompatible coatings. Modern implanted devices with sophisticated electronic functions need printed circuit boards (PCBs) for system integration. Traditional lamination-based PCB technology is not biocompatible
