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 ...

An optical sensor that measures hydraulic pressure in the landing gear of a commercial aeroplane has been developed by the UK-based company Druck. Based on low-coherence-light interferometry, the ...

A fiber pressure sensor boasts a measurement limit that cripples most optical sensors. A new type of optical pressure sensor that is able to operate in extreme conditions has been developed by ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Traumatic brain injury is a major cause of death and disability. When a patient attends an A&E or neurocritical care unit with a head injury, one of the most important parameters to assess injury ...
