I am a student of Electrical Engineering and I am currently working on a biomedical device which stimulates a human arm through functional electrical stimulation technique. Now for instance, if short circuit occurs then,a large amount of current can flow thus, damaging the human arm. So, I want to make something like a breaker myself which will break the circuit right then. My output voltage is around 50 Volts and max output current is 230mAmps.
I considered using a fuse but the problem with a fuse is that it will allow the current flow through to arm atleast once before cutting off the connection. I want to make a limiting circuit that has a low foot print so that the device doesn't look too large. Could you please give me some suggestions? Any help will be appreciated. Thank you! :)
