In this paper, a dual-parameter liquid level and refractive index (R.I.) sensor is fabricated using three pieces of bare polymer optical fibers (POFs), which can independently and simultaneously sense ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

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 ...

Monitoring water quality is essential in order to gain a deeper understanding and ensure the long-term preservation of aquatic ecosystems. In this context, fiber optics represent an innovative and ...

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 special sensor can accommodate various device sizes while recording accurate notes regarding substance levels such as blood, insulin, and IV fluids. A non-contact level sensor does not come into ...
