摘要： A near-eye optic includes a substrate having a clear aperture for propagating light. An inconspicuous electrical circuit is supported by the substrate in the clear aperture of the substrate. The inconspicuous electrical circuit includes a plurality of inconspicuous conductive traces disposed in an inconspicuous pattern and electrically coupled to a plurality of inconspicuous electrical components. The inconspicuous pattern may include e.g. an asymmetric pattern, an aperiodic pattern, a pseudo-random pattern, a meandering pattern, a periodic pattern modulated with pseudo-random perturbations, or a non-rectangular pattern modulated with pseudo-random perturbations.

摘要： In some embodiments, a device, such as a transducer, includes a polymer element disposed between electrodes, and a control circuit configured to apply electrical potentials having the same polarity to the electrodes. A separation distance between the electrodes may be increased by an electrostatic repulsion between the electrodes. Various other devices, systems, methods, and computer-readable media are also disclosed.

摘要： An optical element includes a nanovoided polymer layer having a first refractive index in an unactuated state and a second refractive index different than the first refractive index in an actuated state. Compression or expansion of the nanovoided polymer layer, for instance, can be used to reversibly control the size and shape of the nanovoids within the polymer layer and hence tune its refractive index over a range of values, e.g., during operation of the optical element. Various other apparatuses, systems, materials, and methods are also disclosed.

摘要： An example device may include a light source, an optical element, and, optionally, an encapsulant layer. A light beam generated by the light source may be received by the optical element and redirected towards an illumination target, such as an eye of a user. The optical element may include a material, for example, with a refractive index of at least approximately 2 at a wavelength of the light beam. The light source may be a semiconductor light source, such as a light-emitting diode or a laser. The optical element may be supported by an emissive surface of the light source. Refraction at an exit surface of the optical element, and/or within a metamaterial layer, may advantageously modify the beam properties, for example, in relation to illuminating a target. In some examples, the light source and optical element may be integrated into a monolithic light source module.
