20.1 Introduction

State-of-the-art biomedical systems have enormous potential and have driven the min­

iaturization of several wearables and implantable devices [1]. These miniaturized systems

are responsible for the enhanced life span of patients by offering control, diagnostic, and

treatment possibilities. The first applications of these biomedical devices were primarily
