Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The ...

How large-area electronics can be adapted to create a gigahertz phased-array antenna. The potential advantages of this approach versus discrete components. The test arrangement used and some test ...

Few can question the increasing role of photovoltaic (PV) technology as a scalable, robust means of renewable energy. Yet PV cells are but one element, albeit a critical one, in an overall PV system.

(a) Illustration of tactile challenges faced by Braille beginners. Overlapping receptive fields and strain diffusion produce blurred tactile information, often requiring repeated single‐point ...
