Flat Panel Haptics: Embedded Electroosmotic Pumps for Scalable Shape Displays

[@RobertMilesAI]

Oh also, if you force fluid through an electroosmotic pump, you can detect that electrically, so it's a flow sensor as well for free. You could make one that detects if you press on the bumps

I was thinking the same! Love your work, btw!

I bet Ben of Applied Science would get a kick out of this if he hasn't already seen it

@AppliedScience yo dude

The voltages involved in order to produce a user-detectable displacement are *almost* (but not quite) into extremely-cheap ULN2003 darlington-array territory! now here I go on a saturday, tumbling down the "what very cheap darlington array can I find in volume that'll handle >100V" which is not a question I had ever considered before. I kinda wonder if there's a favorite of the folks running nixie tubes and whatnot which may be suitable...

This is amazing, I just stumbled across this video. I have a huge interest in using membrane actuators in robotics and I am looking for simplified ways of creating and controlling hydraulic flow. Is there potential for the power density and efficiency to be "ok" compared to an electromagnetic prime mover and could the stall pressure be increased by cascading multiple pumps in series?

How could the individual pixels levitate above the surface like with the bridge at the beginning clip? Magnetism? So the pixels next to them are „holding them up“? I know it’s a long way to reach the same level but what are some possible takes?

[@Martin-kn1cn]

Will it be possible to extend the Inflation up to centimeters? Like in the clip at the beginning even?

[@marcinwilczynski9]

Do you know material that can do this?
