Reliable operation of power apparatus and systems depends largely on insulation integrity and insulation design. With increased demand for compact and efficient apparatus, the insulation system is highly stressed electrically and often subjected to various failure mechanisms. In the recent past, there has been considerable research in the development and application of nanodielectrics as novel insulating materials for various applications in power delivery and energy storage.
Nanodielectrics are polymer composites with in which nano-sized organic and inorganic fillers are incorporated into bulk polymers conventionally used in insulation. Despite the accepted use of micro-sized fillers, nano-sized fillers have attracted considerable attention because addition of minuscule quantities of fillers are seen to significantly affect the composite properties. This is attributed to the large interfacial region in nanocomposites, possibly with properties very different from either the bulk polymer or the filler materials.
In this talk, I shall present an overview of the advances made in the area of nanodielectrics. Nanodielectrics have largely been seen to have improved electrical, thermal and mechanical properties and there is increasing body of literature signifying potential. However, the development of dielectrics with tailored properties have continued to be elusive, primarily due to lack of understanding of the nature of the interface. In this context I shall talk about some of the challenges and future directions of research in nanodielectrics.

In this tutorial, an overview of the effective techniques for wireless power transmission (WPT) currently being utilised will be presented. Short-, medium- and long-range WPT technologies based on inductive coupling and radio-frequency (RF) principles (near-field and far-field) will be outlined. With the recent release of wirelessly rechargeable iPhone® and Samsung mobile phones, it is expected that the use of Qi standard rechargeable platforms in the consumer electronics market will rapidly expand. After describing the historical development of WPT technologies and techniques, we will focus on recent advances in WPT for implantable medical applications and structural health monitoring (SHM) applications.
