Israel’s Inteligels has developed a wound covering that can be removed without pain. It is made from a special smart transparent polymer that can be triggered to liquify and does not need to be pulled off. It is based on the work of Daniel Cohn, Professor Emeritus of Chemistry at Jerusalem’s Hebrew University.
