Hello! I'm looking for a substance that can: (1) be turned into a flexible material (e.g., a flexible plastic), (2) is dissolveable in rubbing alcohol but not water (or blood), and (3) safe for a medical procedure .... And, if possible, preferably biodegradable... I know that's kind of a long list, so I'll provide some context. I'm working on a medical device project. The device has to be safe to put on human skin or, ideally, in a human body. The device should be flexible, and dissolveable in less than 10 seconds upon application of rubbing alcohol (or another substance commonly found in hospitals). Because it's for use in medical procedures, the device obviously can't dissolve if blood or water hits it. Any help or direction would be very much appreciated! If this can't be achieved with one material, but would require a combination of materials, please let me know, too! I'll take all the help I can get (I'm an electrical engineer with 0 materials knowledge).
