Ferroelectricity is a property of spontaneous electric polarization that can be controlled by an applied external electric field. Piezoelectricity is a property of electric polarization caused by macroscopic strains, a coupling between the mechanical and electrical behaviors to allow efficient mechanical-to-electrical energy conversion. The non-centrosymmetric material is an important research field because of the associated polarization and its potential application. Among them, piezoelectric and ferroelectric 2D materials have drawn a growing interest in recent years. 8 Particularly, the 2D layered materials with non-centrosymmetric structure have great potential for nanoscale electromechanical systems and electronic device applications. Atomically thin 2D materials exhibit a wide range of unique electrical, 2, 3 optical, 4, 5 mechanical 6, and thermal 7 properties, which do not exist in their bulk counterparts, and the outstanding advantages of properties enlighten the development in light-weight and high-performance multifunctional applications. in 2004, 1 worldwide scientific efforts have been focused on wide range of two-dimensional (2D) layered materials, driven by the fundamental interest and their potential applications. With a bit of luck in the years to come, piezoelecticty will become another weapon which we can use to reduce our reliance on fossil fuels and to derive the energy we need.Since the successful isolation of graphene by Novoselov et al. In many places including Japan’s subway, dance floors across the world and football stadiums, engineers have already put in place piezoelectric floors that use the high volume of footfall to decrease their demand for electricity from the grid. Piezoelectricity is an exciting field of Nanotechnology, and there are already tests being run outside labs to try and harness this form of power. This new research completed by the Berkeley lab, could make this potential technology more viable, as there is now a cheaper source of the piezoelectric material. If you look at the Windstalker technology, you will see that the engineers behind it looked at ceramic piezoelectric materials being positioned within the wind stalks to harness the wind’s energy. The virus itself is shaped as a rod, so when many come into contact, they naturally orient themselves into a amazingly organised film. In addition, as it is a virus, scientists can relatively easily genetically engineer it, thereby improving its piezoelectric characteristics. Firstly, viruses replicate incredibly quickly, producing millions of identical viruses within hours, so your supply is potentially limitless. There are many reasons why this finding could revolutionise the piezoelectric field. Why newly identified viral piezoelectric material could be the answer The final issue is that up to now, many of the starting products needed to produce the piezoelectric materials are toxic and difficult to work with.The current is only produced when there is mechanical stress being applied, so as soon as you stop compressing the material, there is no charge produced.The major issue one is that the quantity of electricity produced is so small, so unless vast installations were set up, it simply would not have the strength to power our latest gadgets.
