Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

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 ...

Researchers developed an extremely sensitive miniaturized optical fiber sensor that can measure small pressure changes. Adding a side hole that runs parallel to the fiber core enhanced the pressure ...

A manufacturer claims that its FOP-F125, shown above on a 0.02-in. needle, is the smallest fiber-optic pressure sensor yet developed. Constructed with a diameter of 125 µm, a fiber-optic pressure ...

Chemists at Johannes Gutenberg University Mainz (JGU) and at the Université de Montréal in Canada have developed a molecular system capable of very precise optical pressure measurements. The gemstone ...
