Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

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 ...

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 ...

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 new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2024.240005, discusses advances in optical micronanofiber enabled tactile sensors and soft actuators. As a perfect combination of ...

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 ...

Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' ...

Integrating an optical touch switch in their compact, surface-mount packages, the SFH7740 and SFH7741 proximity sensors use distance measurements to detect a mobile device’s operating status without ...
