A new publication from Opto-Electronic Advances, DOI 10.29026/oea.2022.210101 discusses a highly sensitive and fast response optical strain sensor. The authors of this article propose a highly ...

Fig. 1 Overview of the OFN sensor. (A) Schematic diagram of the OFN sensing system; (B) Photographs of the output light when the sensor was untouched, (C) subjected to normal force, and (D) subjected ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

A new imaging technology developed at the University of Connecticut promises to rewrite the rules of optical imaging, ...

Complex fluids, such as polymer melts and concentrated suspensions, are foundational materials for industrial products, ...

Understanding acoustic feedback in hearing aids. Power consumption challenges in hearing aids. Functionality integration and its impact on energy consumption. The benefits of using photoreflectors for ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

Ocean-borne phytoplankton collectively absorb almost as much carbon dioxide as all the trees and land plants on Earth. Besides giving seawater a greenish tinge, the plankton have a significant impact ...
