HIGHLIGHTS
- who: Wei Feng from the (UNIVERSITY) have published the paper: Heterostrain-enabled ultrahigh electrostrain in lead-free piezoelectric, in the Journal: (JOURNAL) of 23/Dec/2021
- what: The authors report one strategy to enhance the electrostrain via designing "heterostrain" through atomic-scale defect engineering and mesoscale domain engineering. The authors demonstrate practical solutions for achieving high electrostrain in low-cost environmentally piezoelectric for various applications. The authors report a phenomenon of "heterostrain" in BNT-based piezoelectric ceramics (Fig 1c). The authors show that the strain along the negative direction of the electric field becomes negative . . .
