A single phototransistor mimics retinal bipolar cell function while detecting visible and infrared light, enabling low-power image processing through programmable ON and OFF photoresponses. (Nanowerk ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

The schematic diagram of the ultra-sensitive optical immunoassay platform, which comprises two pivotal components: one dedicated to establishing highly sensitive sandwich immunocomplexes for ...

Researchers from the Department of Physics in the College of Science and the James C. Wyant College of Optical Sciences, all at the University of Arizona, have demonstrated a way to manipulate ...

Editor's take: The University of Arizona could become the birthplace of the world's first petahertz-speed transistor. If successful, this research work could mark the dawn of a new era in computing, ...

Researchers demonstrated a way to to manipulate electrons using pulses of light that last less than a trillionth of a second to record electrons bypassing a physical barrier almost instantaneously -- ...

Researchers demonstrated a way to manipulate electrons in graphene using pulses of light that last less than one thousands trillionth (one quadrillionth) of a second. By leveraging a quantum effect ...

What if ultrafast pulses of light could operate computers at speeds a million times faster than today's best processors? A team of scientists, including researchers from the University of Arizona, are ...

The devices, which operate on a heterojunction-gated (HG) structure, demonstrate high responsivity and detectivity while maintaining a simplified fabrication process. This approach avoids the ...

A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...
