Bioimpedance and Bioelectricity Basics, 3rd Edition

Chapter 3

Dielectrics

Abstract

This chapter deals with the definition of the basic concepts such as bioimpedance, bioelectricity, conductor, dielectric, and so on. It gives examples of active and passive electrical properties of biomaterials and also provides an overview of what is covered in the rest of the book.

A dielectric may be defined simply as a volume of material placed between the plates of a capacitor for examination by an applied electric field. Traditionally, there is an important difference between dielectric and bioimpedance measurements with respect to the role of water. Etymologically, a dielectric is a material that the electric field penetrates (Greek dia meaning through). ...
