The camera is, after all, a mechanical device: The lens records whatever appears before it with a cold yet democratically unflinching eye.
" Find a free app that measures objects using the device's lens.
Nanoscale patterning used in disk media is a promising technology for storage devices (patterned media) and optical devices (Fresnel lens, X-ray zone plate).
DE actuators have promising applications in many emerging fields such as biomimetic robots, haptic devices, tunable lens, and loudspeakers.
These projection ratio and pattern widths were decided considering the present applications to fabrications of micro-fluidic devices and lens arrays.
In the same way that the transition from film to digital is now taken for granted, the shift from cameras to networked devices with lenses should be obvious.
As an important category of plasmonic devices, plasmonic lenses based on thin nanostructured metallic films were proposed and developed [11 17].
As an important category of plasmonic devices, plasmonic lenses based on thin metallic films were developed [15 21], being an alternative to the conventional dielectric-based refractive lenses.
Fungi can form biofilms on biomaterials commonly used in clinical practice (intravascular catheters, dentures, heart valves, implanted devices, contact lenses and other devices) and are associated with infections.
In this article, we highlight the recent advances in hydrogels, bioengineered prosthetic devices, contact lenses, and drug delivery systems for corneal regeneration.
