A new paper, co-authored by Electrosciences, points to new ways to control high powered sonar projectors using some of the newest single crystal piezoelectric materials that are becoming commercially available. Experimental measurements taken by Electrosciences in collaboration with the UK XMaS beamline at the ESRF, France, highlights the requirement to control the pre-stress needed to achieve the very high piezo activity needed.
