Abstract:
Disclosed herein are display devices including a flexible electronic display layer that is configured to emit an image. The flexible electronic display layer can, for example, be configured to releasably couple with a flexible supporting layer to increase stiffness of the flexible electronic display layer. Methods of making and using the display devices are also disclosed.
Abstract:
Sensors for detecting at least one electrolyte in a conductive solution are described. The sensors may include a dielectric substrate and a resonator having a resonance characteristic and configured to generate a signal in response to an interrogation signal. The resonator may include a conductive layer in contact with the dielectric substrate, at least one layer of nanotubes provided on the conductive layer, and a dielectric layer at least partially encapsulating the nanotubes.
Abstract:
A tunable spectrometer is described. A tunable spectrometer may include an optical filter, having a first reflector stack and a second reflector stack separated by a half-wave spacer, a heater, a heat-sink and a detector array. At least one of the first reflector stack, the second reflector stack, and the half-wave spacer is made from a thermo-optic material. The heater and the heat sink are separately in contact with at least one of the first reflector stack, the second reflector stack, and the half-wave spacer. The detector array is configured to collect an output from the optical filter. In various embodiments, the heat and the heat sink may be separated by an optically transparent thermal isolator.
Abstract:
An optical component is disclosed, as well as articles of manufacture, methods for forming, and methods of operating thereof. The optical component may include a plurality of patterned two-way shape memory alloy portions. Each patterned two-way shape memory alloy portion may include a reflective surface and a temperature adjustment element. Each patterned two-way shape memory alloy portion may be individually configured to flex to a first bend angle at a first temperature and a second bend angle at a second temperature.
Abstract:
An air purification system comprises a chamber having an air inlet and an air outlet, a plurality of flexible wires hanging from a ceiling of the chamber, a spray mechanism configured to spray droplets in the chamber, and a sound wave generator configured to generate a standing sound wave in the chamber. During operation of the air purification system, the plurality of flexible wires are elastically deformed by the standing sound wave generated by the sound wave generator such that portions of the plurality of flexible wires converge at nodes of the sound wave, and also the droplets move to the nodes of the standing sound wave, while trapping particles in the air during the movement to the nodes. The droplets collide against and are adsorbed to the plurality of flexible wires at the nodes of the sound wave.
