PROCESS FOR MANUFACTURING A PYROELECTRIC AND/OR PIEZOELECTRIC DEVICE

摘要

The invention relates to a process for manufacturing a piezoelectric and/or pyroelectric device comprising a polyvinylidene fluoride film (16), the process comprising a step of forming at least one portion (14) of a layer of a solution comprising a solvent and a compound comprising polyvinylidene fluoride and a step of irradiating the portion with pulses of at least one ultraviolet radiation (18). The irradiating step enables the formation of at least two β crystalline phases having different orientations.
