摘要： An object is to provide an organic piezoelectric film with a high level of piezoelectricity, a high level of transparency, and a low level of retardation. The organic piezoelectric film of the present disclosure has a total light transmittance of 90% or more, an internal haze value of 0.2%/µm or less per unit film thickness or an internal haze value of 4% or less, piezoelectric constant d33 of 13 pC/N or more, and a retardation within the range of 0.01 to 10 nm/pm per unit film thickness or a retardation within the range of 0.1 to 900 nm.

摘要： The invention discloses a system and method for manufacturing piezoelectrics. The system includes at least a first roller (330a) and an end roller (330b); a continuously advancing printable substrate roll (12, 204, 306) extending at least from the first roller (330a) to the end roller (330b) as the first and end roller turn; at least one printer configured to print piezoelectric material (206, 214) onto the continuously advancing substrate roll (12, 204, 306) to form a plurality of the piezoelectrics; and an electric field generator that is configured to poll the piezoelectric material (206, 214) as the continuously advancing substrate roll (12, 204, 306) is rolled from the first roller (330a) to the end roller (330b). The electric field generator is configured to generate the electric field (310) at ambient temperature (312) or at above-ambient temperature (312). The system further includes a cooler (316) configured to drive the ambient temperature (312) or at above-ambient temperature (312) to below-ambient temperature substantially immediately following the electric field generation.
