  • Patent number: 9901881
    Abstract: Described herein is a method for altering the characteristics of a membrane comprising a dielectric material. The method comprises heating the membrane and applying an electric field in a direction out of the plane of the membrane to at least a portion of the dielectric material. At least a portion of the dielectric material becomes aligned with the applied electric field. In some embodiments, the membrane is piezoelectric and application of an electric signal to the membrane causes out of plane movement of the membrane. Also disclosed are membranes and systems and apparatuses comprising such membranes.
