Abstract: An optical transformer includes a light source and an array of photovoltaic cells optically coupled to the light source, where at least a portion of the photovoltaic cells are connected in series. An optical connector such as a waveguide or an optical fiber may be disposed between an output of the light source and an input of the array of photovoltaic cells. Configured to generate a high voltage output, the optical transformer may be configured to power a device such as an actuator that provides a tunable displacement as a function of voltage.

Abstract: A graded-index optical element may include a nanovoided material including a first surface and a second surface opposite the first surface. The nanovoided material may be transparent between the first surface and the second surface. Additionally, the nanovoided material may have a predefined change in effective refractive index in at least one axis due to a change in at least one of nanovoid size or nanovoid distribution along the at least one axis. Various other elements, devices, systems, materials, and methods are also disclosed.

Abstract: A liquid dispersion includes a matrix phase of polymerizable material and at least 10% by volume of solid conductive particles distributed throughout the matrix. The conductive particles may have an average particle size of less than approximately 100 nm, and the liquid dispersion may have a viscosity of less than approximately 100 Poise. Such a liquid dispersion may be printed or extruded and then cured to form a solid thin film. The content and distribution of conductive particles within the thin film may reach a percolation threshold such that the thin film may form a conductive layer. Polymer-based devices, such as nanovoided polymer (NVP)-based actuators may be formed by co-extrusion of a nanovoided polymer material between conductive polymer electrodes.

Abstract: An actuator assembly includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and an electroactive polymer layer disposed between the primary electrode and the secondary electrode, where the electroactive polymer layer includes a non-vertical (e.g., sloped) sidewall with respect to a major surface of at least one of the electrodes. The electroactive polymer layer may be characterized by a non-axisymmetric shape with respect to an axis that is oriented orthogonal to an electrode major surface.
