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 ...

Researchers have developed a flexible optical touch sensor that can simultaneously detect the strength and location of ...

Built using polymer waveguides embedded in silicone, the technology could transform robotics, prosthetics, and next-gen ...

Imagine a touch sensor so thin and flexible it can feel not only where you press but also how hard. Scientists in Japan have ...

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 ...

The Series 1010 synthetic optical-fiber sensor does contact-level detection in all nonmilky-white liquids. The unit features an AISI 303-stainless-steel housing, a scratch-resistant glass prism, and ...

Although optical fibers are highly effective at data transmission, they're also relatively brittle. An experimental new type of optical fiber addresses that limitation, by incorporating a core made of ...
