| Description | Through mathematical modelling, it has been possible to highlight outstanding candidates that possess a much higher sensitivity to external stimuli compared to other piezoelectric materials (ie materials that can convert mechanical energy into electrical energy and vice versa). The findings of this modelling suggest that the solid solution of bismuth ferrite (BiFeO3) and lead titanate (PbTiO3) in single crystal form exhibits a "sensitivity coefficient" more than twice the value of previously characterised materials. Furthermore, this material is of significant interest in applications which require harsh environments as the temperature in which it loses its piezoelectric properties (~630 degrees celsius) is significantly larger than market dominant piezoelectric materials which are often limited to 200-250 degrees celsius. |
| Exploitation Route | The results of mathematical modelling highlight bismuth ferrite lead titanate as an outstanding candidate for high sensitivity piezoelectrics, which may pave the way for others to experimentally validate this hypothesis, and incorporate these materials into devices to be used in passive sensors used in the fishing, security, automotive and oil and gas industries as listening devices. |
