Electric Field Induced Tunable And Metastable Remanent Strain And Remanent Permittivity In Ferroelectrics

Current ferroelectric applications utilize linear ferroelectric properties from a polarized state so that when an electric field is applied the piezoelectric strain and permittivity change linearly with the applied electric field. However when the electric field is removed the strains and permittivity values return to their initial state. As a result electrical power is required to maintain the new strain and permittivity states. This produces problems in many applications where long term changes are required or where power is a major issue.

Benefits

1) Permanent strain and permittivity 2) Tunable permittivity 3) Reduced power consumption
