A lot of it is limited by the amount of control an amputee would have. It’s hard to create something that is both stronger than the human grip with the same amount of control over how you exert that strength.
Some of the older myoelectric pincer type terminal devices had a slip reflex built into them. Where if the sensors in the pincer felt an object slipping, it would crank down harder. It had an average grip strength, but because of the nature of how pincers work, all that power was exerted into a much smaller inflexible area.
It worked fine on solid objects, but if you ever tried to use it on a person and that person tried pulling away…you could give someone a really really unpleasant pinch.
