Interesting! But after a bit of research I find nothing of the sort: either they are device that prevents flexion up to a certain angle but do not help movement or they are active motor-aided designs. Would you have an additional keyword or a link?

You basically found it. They relieve pressure on the joints, in addition to locking certain angles that hurt. Springs would essentially do the same thing, but more dangerous.

Helping upward movement is the whole point of the contraption, but thanks, I'll probably buy some of these and strong springs to do some tests.

Springs are some of the most dangerous things in engineering, especially strong ones. There is a reason why you don't fuck with the garage door. Anything happens - the person falls over, a bicycle hits them, etc - and it's a tragedy waiting to happen

This is how engineers die:

In 1940, at the age of 51, Midgley contracted polio and was left severely disabled. He devised an elaborate system of ropes and pulleys to lift himself out of bed. On November 2, 1944, at the age of 55, he was found dead at his home in Worthington, Ohio. He had been killed by his own device after he became entangled in it and died of strangulation.

Safety? What's that?

Considering that he also invented leaded gas and freon it's almost more like his bad inventions finally caught him personally

Not to discourage creativity, but I think there was a whole documentary about how bad an idea spring loaded exoskeletons are. Five Nights at Freddy's or something like that?

Post your progress and results on the community, I'm curious!
