Hey everyone, We are currently working on a project to make a kind of sleeve that can suppress a big part of the wrist tremor that Parkinson patients or people with other diseases have. We are trying to decide to make this a partially active system, with only adjustable damping, or a fully active system with actuators that uses forces to counteract the tremor (out-of-phase). The problem is that we don't find any actuators that would be able to do this. It has to be very light and small, so that it could fit in just a normal long sleeve. And it would have to be able to deliver the needed forces. We were looking at Electroactive Polymers, because these are sometimes used as artificial muscles, but it seems these wouldn't be able to deliver the necessary forces. We were wondering if anybody here knew about a kind of actuator that would be an option in this project? Or maybe a kind of electroactive polymer that could work? Thanks to everybody who wants to help us realizing this product that could help many people around the world!
