Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

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 ...

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 ...
