Characterization of a planar microcoil for implantable microsystems

Characterization of a planar microcoil for implantable microsystems

This paper discusses the modelling, design and characterization of planar microcoils to be used in telemetry systems that supply energy to miniaturized implants. Parasitic electrical effects that may become important at a.c. frequencies of several megahertz are evaluated. The fabrication process and electrical characterization of planar receiver microcoils will be described, and it will be show...

Implantable Microsystems for High-Resolution Interfacing to the Brain

Designing and Fabrication of a New Radiofrequency Planar microcoil for mini-Nuclear Magnetic Resonance

Introduction Radiofrequency planar microcoils are used to increase the resolution of magnetic resonance images of small samples. In this study, we aimed to design and fabricate a spiral planar microcoil constructed on a double-sided printed circuit board (PCB). It has four rings with an internal diameter of 241 microns tuned and matched at 63.8 MHz. Materials and Methods To achieve the maximum ...

Wireless Telemetry for Implantable Biomedical Microsystems

Rapid development of microelectronics during the past years allowed the emergence of high-performance implantable biomedical microsystems (IBMs). Nowadays, these systems share many features and basic components, and are being used in different applications such as neural signal recording, functional muscular stimulation, and neural prostheses. Due to implant size limitations in a wide range of ...
