Have been messing around a lot with EMG lately and one of the biggest problems I've faced is with the electrodes. Currently all the electrodes available on the market are disposable wet electrodes that generally only last for one use which is a problem for ongoing projects I'd like to be longer lasting and is also a hassle to have to try and find the exact same spot again every time so as to not skew the results.
The way I see it, there are two main options to get around this issue. Either to come up with cheap and easily manufactured reusable dry electrodes or to design small implantable ones. I think the former solution would be easier but I have no idea how to make that work. The implantable ones would be a lot easier said than done as you'd have to make them wirelessly transmit the data and because of the small size would likely have to have them wirelessly powered as well. And then you still have to ensure that they're both conductive and biocompatible.
Anyone got any ideas or suggestions?
