Inside a silicon MEMS flow sensor
As part of a recent project here at Microncubed we had the opportunity to tear-down and look inside a silicon MEMS flow sensor. Flusso, a company based in Cambridge, U.K. developed this compact sensor in order to measure air and gas flow. A team experienced with microscale thermal devices founded Flusso in 2016. And in…

How to measure diffusion coefficients
‘Evidently, the makers of scent owe their livelihood to close encounters, wind and/or convective flow’. Those are the Feynman-esque words of the late Prof. Howard Berg, when discussing the diffusion of perfume in his 1993 book Random Walks in Biology (RWB). While diffusion contributes to molecule transport there and elsewhere, other effects can mask it.…
