Projects per year
James's research is in the development of ferroelectric composites for sensing, piezoelectric energy harvesting and energy storage applications. This includes:
- Understanding the interaction between constituent phases on the inherent properties of the active phase using a combination of numerical modelling and experimental techniques
- Tuning effective properties of materials depending on specific application and environment
- Developing advanced fabrication methods, primarily of porous ferroelectric ceramic matrices, to produce composite structures that maximise performance
