Electronic devices and components are getting extremely miniaturized. To make the devices even smaller and ubiquitous in the future, it will be insufficient to just squeeze as many components as possible into a small space because there is a physical limit of the space and there will be inevitable interference between components if they are placed too close to each other.
This project will contribute towards solving the problem by fundamentally UNIFY (project acronym) two significant but contradictory components, piezoelectrics and photovoltaics. Piezoelectrics convert energy between its kinetic and electrical forms and photovoltaics (or optoelectrics) convert energy between its optical and electrical forms. They are widely used in modern electronics of energy, smart sensing, medical, automotive, space industries and so on. These two types of components have not been believed to be able to reach top performances simultaneously in the same component and, UNIFY is seeking to change this view. The project attempts to replace the ever-separate components with a single, universal one, where a success will revolutionize the field from a potentially fourth dimension – material composition and microstructure.
