Light speckle fluctuations, a noninvasive proxy for cerebral blood flow index (CBFi), are quantified by diffuse correlation spectroscopy. However, this conventional technique provides marginal brain ...

A tiny fibre-optic sensor has the potential to save lives in open heart surgery, and even during surgery on pre-term babies. The continuous cardiac flow monitoring probe is a safe way to give a ...

I want to know what I am breathing and I don't leave home without it. We talk a lot about air quality on TreeHugger, and lately we have been preoccupied with particulate matter, the tiny bits called ...

A team of scientists have developed the thinnest and most sensitive flow sensor, which could have significant implications for medical research and applications, according to new research. A team of ...

Engineers in search of a low-cost flow verification solution for process analyzer sampling systems that is suitable for hazardous plant environments will be pleased to learn that the advanced Model ...

I recently got a chance to design a simple device to monitor air flow in a vent. I was foiled, as the proposal demands a cheap model based on a common PC cooling fan as the air flow sensor. Although ...
