A 'flesh interface' could potentially describe a very strange and unique concept. It might be a new and emerging idea in the fields of biotechnology or human - machine interaction. However, without further clarification, we can only speculate. It could be that it refers to an interface that is designed to interact with living tissue, like a device that can read nerve signals directly from the flesh or a material that can be implanted into the body to create a seamless connection between the biological and the artificial. But again, this is all speculation without more details about what this 'flesh interface' actually is.
