High-strain Peano-HASEL actuators

- The Keplinger Research Group at the University of Colorado Boulder has developed a type of muscle-mimetic actuator, termed high-strain Peano-HASEL, that achieves powerful and high-speed linear contraction greater than 20%. These devices can be used as a bio-inspired artificial circular muscle (ACM) that operates as a soft pump. Additionally, high-strain Peano-HASEL actuators can be paired with pulley systems to boost the actuation strain to over 40%.

Great achievement, how many watts are used to lift that 20 g of load?
this is terrifying, because its voltages have to be 1-10kV to produce such strong electrostatic attraction. maybe it's even more than that if you look at gigantic plastic margins they have in all those examples to prevent it arcing around between electrons, so maybe the voltages are even as high as 20-50kV.
however, I bet it's pretty efficient and has a good response time.
How much noise does the setup produce? Is the electric effect that causes contraction silent?
Keep it up. When is a commercially available robot muscle going to be available? Or maybe a licensed kit with detailed instructions on how to make these?
Would miniaturising the pockets reduce the voltage requirement?
Really cool stuff since the ted talk?
What electrodes are used?
10kV.....well that's not practical.
So depressing to see it requires 1K+ volts to operate.. cute but not practical.
Is there nothing out there that shows promise?
Maybe stop whinning and research it yourself, then? If you're gonna complain about cutting edge, brand new tech
Could just insulate the HV parts sufficiently or I'm sure there are environments in which having such a high voltage is negligible though surely?
voltage can easily be stepped up to a few thousand volt even on battery power... also 5kv is still pretty easy to insulate
