ABSTRACT
This chapter provides an overview of some of the applications of wireless powering and focuses on far-field remote powering for implantable applications using radiative electromagnetic fields. Wireless powering has benefits in a variety of different areas but has the potential to revolutionize the field of medical devices. Analytical and simulation models are presented to help illustrate and gain an intuitive understanding of RF propagation through tissue. The chapter focuses on the optimization of the radiative far-field powering through an analysis of RF propagation through tissue, state-of-the-art simulation and modeling, and proper design of the electrical components. A miniature device described in takes advantage of this wireless powering technique to achieve a fully active intraocular pressure monitoring device with an integrated micro-electromechanical systems pressure sensor, capacitive power storage array, and application-specific integrated circuit, and antenna all assembled into a biocompatible package.
