We have been very fortunate to have receive funding for our project submitted to the m-era.net 2022 call! The project: Defective metal oxides as the next generation of lead-free piezoelectrics for ultrasonic actuators (DEMETRA) has been submitted in collaboration with strong partners: DTU (Vincenzo Esposito - coordinator), CTS Ferroperm - former Meggit, a Danish producer of piezoelectric components, and Federal University of ABC (UFABC) from Brazil! Within this consortium we will push the limits of electrostrictive materials based on ceria to a new level.
Short abstract for the public (from the m-era.net results document):
Electromechanical smart materials are like muscles that change their size and exert forces under electrical stimuli. They are in sensors and medical devices and are essential for future technologies. Despite their importance, the best-performing material is an old technology: lead-based piezoelectrics, which is highly toxic. A new class of materials, non-classical electrostrictors, have been discovered. These outperform lead-based piezoelectrics and are biocompatible and inexpensive. However, we still need to assess them for "fast" ultrasounds. Objectives: #1: Understand how nonclassical electrostrictors work at the atomic level. #2: Optimise their properties in the ultrasound to prove their industrial competitiveness. Potential applications: Target applications are echo-scan, lab-on-chip, adaptive lenses and ultrasonic manipulators. Impact and potential benefits: We will impact society through industrial innovation and environmental sustainability
