Here is a design concept for a cheap single point optical liquid sensor that can detect the presence or absence of certain colored liquids inside a transparent tube. It can be tailored to output a ...

a, fabrication process of humidity-responsive CLCP films with geometric phase encoding. b, Photo of the films cured at 65℃. The scale bar is 1 mm. Sensing technology, integral to environmental ...

A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next-generation optical sensor technology capable of precisely detecting not ...

Artificial Intelligence (AI) and photonic sensing technologies are marching toward a convergence yielding intelligent high-performance sensing systems 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 ...

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' ...

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 ...
