I fell in love with your idea and work just a week ago; thanks so much for the update and Intel. VHB tape a unit to the bottom of a foam glider? i would love to see this tech take flight with some sort of drone... even if it needed a slingshot launch assist. I suppose this design is also a type of innately explosion proof ventilation, and might win you a big methane or fossil fuels type client? what happens when you try to drive fluid with it? it would be fun to measure performance while in the dynamic environment of a supercritical gas chamber. send one to collab with Ben over at the Applied Science channel!

I wonder if this would be useful in a VR application, maybe using it for creating a wind like effect on your face, but I am unsure if this device would have any significant drawbacks compared to regular fans. From what I've seen (very little) most start-ups developing these sorts of VR add-ons use regular fans. One obvious advantage is the immediate start up of the piezoelectric fan, which means you can create the "wind effect" without any start up delay.

@@thebaddestogre-3698 Yea, I was thinking that it would be best to have a minimum of 3→4 of these solid state fans. Aimed partially at your neck, you'd be able to give more accurate directional wind effect. If you used binaural audio to create a truly 3D wind effect, the player would be able to tell exactly which direction that the wind is coming from. I'm also assuming that these solid state fans can get a lot smaller than traditional fans.

@@thebaddestogre-3698 This fan has 0 static pressure. meaning it moves air but you wont really feel the air. Its boggling to see it move smoke as well as a normal small slow fan but feel only the tinniest amount of force from the blowing air. so unfortunately it would not work in VR plus it would take way more room than a small fan.

So cool. I would assume it would be extremely cheap to mass produce on a large scale. Seeing quarts watch scale ability. But could the “fin” be reshaped to push more air. I was thinking in air conditioning/heat pumps. Would this be sufficient. There’s a constant market for more efficient seer rates. If the cooling fans would run off milliamperes that could be a game changer. Or even the fins themselves become the mechanics for moving air. That could also make the heat exchanger “potentially” more compact.

Hi, the geometry of the fan looks very simple. Is this to keep the flexing within elastic deformation or is it a different reason? Could the fan be a different shape to maximize airflow / make more white noise than a single audio frequency? What are the effects of putting fans like these in parallel or series? Thank you

The thing has only one resonant frequency, so why do you want to put other frequencies through it? Other than curiosity of course ;) If ou feed it a nonresonant frequency then you simply make it inefficient.
