The movement-creating device is called a "hydraulically amplified self-healing electrostatic" actuator. That's a HASEL (pronounced "hey-zuhl") actuator or muscle, for short. The pump-free devices are pouches made of the same inexpensive plastic that makes up potato chip bags and filled with an electrically insulated liquid, similar to canola oil. The devices change shape when voltage is run through them, and the malleable oil gives the mechanism the potential to self-heal.
"You can control it with only two wires," Science paper lead author Eric Acome says, referring to the wires used to power the electrodes. "We don't need to have some sort of external equipment."
The researches outline different applications of the muscle, which is thin, transparent, and flexible. One design is a donut-shaped muscle with electrodes placed on either side of it. When the device is electrified, the oil inside it moves, changing its shape to mimic gripping.
Another muscle design is made from stretchy, ionic conductors with a liquid pocket inside. When electricity is applied to it, the muscle spasms, which can lift a gallon of water or flex a mechanized arm.
Another design, dubbed a Peano-HASEL actuator, is made of three small, rectangular pouches strung together. The liquid-filled device contracts under a kick of voltage, much like a biological muscle. The movement is so gentle it can grasp plump raspberries or raw eggs without crushing them.

But I see how it could be mis construed.
Or melons?
Not madame..sorry about that.
I don’t have much but am proud if every foot of it.
No wonder none of us are getting any these days. Who can compete with that?
That looks like somebody I know who hasn’t been laid in about 4 years.
LOL!
Ribbed....yeah i see what you did there...
So it is a “bonemaker”?
Heck of a Jock Strap you have there...
Cool servo.
ligaments join bone to bone. All they have to do is stabilize. Much simpler than muscle. When one of our dogs tore a ligament in a knee, the vet surgeon used fishing line as a replacement. I’m sure there is something more sophisticated for humans.
A guess: the hardest part is attaching the replacement to the bone in the proper place. Maybe they graft past the tear or weak spot, attaching to the still-intact portion of the ligament?
Docs here probably know the answer.
Meant tendon....
Hey Joe. What do ya’ know.
Gym stocks or gym socks?
The gym socks part is a subtle call out to post #2 ;-)
They can do that, too. Grafts, auto-transplants, synthetic and grow ‘em in a dish or combinations of those techniques.
