End of stealth aircraft

It used to be that you needed a huge cellphone network to start mapping changes in air currents, but now these guys have developed a sensor that can measure the movement and displacement of air particles using a sensor smaller than a matchstick head!

The Microflown

The Microflown is the worlds first and only MEMS technology based sensor that can measure the acoustic particle velocity. By measuring the temperature difference in the cross section of two extremely thin platinum wires placed in parallel, this extremely fast mass flow sensor is capable of monitoring the movement of air particles. Any sound field is described completely by both the (scalar) value sound pressure and the (vector) value acoustic particle velocity. Understandably, acoustic testing becomes much easier if both acoustic quantities can be measured. But the Microflown sensor platform can also be used to measure:

*

structural velocity

*

sound pressure

*

temperature

*

DC flow

*

acceleration
