HASEL actuators with muscle-like performance

The Keplinger Research Group at the University of Colorado Boulder has developed a new class of soft electrically activated artificial muscles, called HASEL (Hydraulically Amplified Self-healing ELectrostatic) actuators, which exceed or match the strength, speed, and efficiency of biological muscle. HASEL devices are powerful enough to lift a gallon of water, yet offer the versatility to perform delicate tasks like grasping small fruit or an egg. Also, HASEL can self-heal from electrical damage, self-sense position, and operate at high-speeds, all while being made from inexpensive materials like silicone rubber, hydrogel, and vegetable oil.

[@Turboy65]

The future of robotics lies with piezoelastic polymer muscle analogues. They will render all other robotic motion and strength technologies obsolete, and they are what you should be focusing on rather than this dead end technology. With piezopolymer muscles, all that is needed is a control loop (since they would have position and force sensors in them, most likely) and power connections. No pumps, no gears, no servos, nothing but the muscle, its attach points, power, and data cables. Really straightforward, and capable of very efficient force generation with precise positioning control.

[@MrGoatflakes]

So is this, it also doesn't need pumps, just plates and a voltage. Just like piezoelectrics. It is also an electrostatic motor just like anything piezoelectric. Which means both require far more electrical energy per work done.

[@MrGoatflakes]

Also it can also sense its own position by either capacitance or stored voltage. Just like a piezoelectric element.

One of the weak points of these actuators is they require an extremely high (and unsafe) voltage to operate with good performance (kilovolt range IIRC). I don't think they actually require insanely high power though, just high voltage.

So basically it has a plastic membrane. Filled with a quick dry fluid for not self healing probably more akin to self patching. And compresses via electromagnet.

[@KETODZN]

I love how this shows the potential for the future in medicine and in the industry, and at the same time it just proves how wonderful nature is, that we have muscles that work a similar way but its a mixture between electricity, chemistry etc. I mean muscles are extremely flexible and can tighten so extremely much and become solid like high density plastic... we can lift 50-200KG depending on the type of movement and the amount of muscles and propably more if we count our legs as lifting force... And all that with such little space. i mean yeah, mechanics can do it more compact and stronger, but we just need a bit of energy to do it.

Can I use this with my humanoid ?

[@Gameweasel]

I love the advancement here. I'm not a scientist but you have no idea how much of my brain and daydreams are spent trying to think of ways to make humanoid style robot muscles. Can I ask.. Is the oil itself reacting to the electrodes or is it that the electrodes are attracted to each other when voltage is applied, causing a simle liquid displacement? The news artilces made it sound like the liquid spasms, but from the video here it looks like the liquid could almost be anything. On the other hand the "self-healing" description makes it seem though as if the liquid itself is also reacting.

[@Fennecbutt]

Liquid displacement...the self healing is the elastomeric coating being healed by the fluid drying around the leak and hardening/sealing upon exposure to air (from what I can tell).

[@Wol333]

Is that using castor oil?

[@tgmorrissey]

great questions. This is using, vegetable based transformer oil, but castor oil would work too (castor oil is a little viscous which hinders performace) you can find more info on our groups website, links in description above.

[@TheNameOfJesus]

It's seems so obvious, now that I've seen it, that an electric motor could move liquid rather than solid (although the skin of the bags are solid in this motor.) Quite an interesting accomplishment. I'm sure it will find a place in the wide world of electric motors. How quiet is it? Can you include a video with sound? Nice to see it can also be a servo.

[@TheNameOfJesus]

With all due respect, the definition of an electric motor is "an electrical machine that converts electrical energy into mechanical energy" which describes this machine accurately.

[@tgmorrissey]

This system is based on electrostatic principles and is very quiet, no spinning fans or anything to make noise. The only noise it makes is if it operates so fast it acts as a speaker.

[@TheNameOfJesus]

Thanks. I see someone mentioning that voltage is an issue. I guess for any consumer application you would need to get this down to 110 volts A/C. You don't have to tell us how soon that will happen, but can you give a hint/clue as to whether it's in your plans?

How dangerous is this 10kV around humans?

[@tgmorrissey]

Hi yazicib1, Voltage alone is not dangerous to humans. You actually generate static electricity on the order of 10kV regularly when you remove a sweater or rub your feet on a carpet rug. It is electrical current (charge) that could potentially be dangerous. Luckily HASELs, operate at relatively low charge and do not present a major danger at all. There will be more studies about this in the future but essentially, they are safe to be around humans. Thanks for the great questions- Tim

[@Fennecbutt]

Maybe as bad as a bad static shock I suppose, but constant. KInd of like a bad version of one of those shock/joke toys. It can all be insulated away though I imagine. Only problem with HV supplies is the terrible high frequency whine that they generate...

[@isaiahphillip4112]

@@tgmorrissey You do know that voltage is what produces current right? (And vice versa). Also current isn't just charge, is the rate of flow of charge. V=IR and I=V/R If a human (resistance of 100kilohms best case scenario, it's generally substantially lower) completes a circuit between a 10kV potential difference there would be 100 milliamps of current which certainly isn't pleasant and could be deadly for some.
