摘要： A liquid lens with flexible transparent active layers on both sides of a fluid is transformed along two distinct deformation axes. The flexible transparent active layers include piezoelectric materials that actuate the lens in response to applied voltage(s). The piezoelectric properties and actuation mechanism of the transparent layers are arranged to deform the lens cylindrically along different axes resulting in a net spherical deformation or a combination of spherical and cylindrical deformation with substantially less distortion than spherically deforming layers. The piezoelectric active layers may be polymer or ceramic with isotropic or anisotropic mechanical stiffness. Alternatively, a pair of transparent, internal layers are positioned between the front and rear surfaces. The active layers, front and/or rear, are dual layers affixed together with an adhesive or single layers.

摘要： According to examples, an energy harvesting component for an optical device having an illumination source emitting unused light is described. The apparatus may include a light source to generate and transmit display light comprising at least one beam of light and an illumination source component to receive the at least one beam of light and to diffract the at least one beam of light in a first direction and an opposing direction. The apparatus may further include and an energy harvesting component to receive and absorb the at least one beam of light diffracted in an opposing direction and to convert the at least one beam of light diffracted in an opposing direction into electrical energy.

摘要： A mechanically and piezoelectrically anisotropic polymer thin film may be formed by gel casting a solution that includes a crystallizable polymer and a liquid solvent. The solvent may be configured to interact with the polymer to facilitate chain alignment and, in some examples, create a higher crystalline content within the cast thin film. The thin film may also include up to approximately 90 wt. % of an additive and may be characterized by a bimodal molecular weight distribution of a crystallizable polymer where the molecular weight of the additive may be less than the molecular weight of the crystallizable polymer. In some examples, the polymer(s) and the additive(s) may be independently selected from vinylidene fluoride, trifluoroethylene, chlorotrifluoroethylene, hexafluoropropene, vinyl fluoride, etc. The anisotropic polymer thin film may be characterized by an electromechanical coupling factor (k31) of at least 0.1.
