Amplify the dimensions and strength and bounceyness etc of a Japanese fan and shape is so that it can both fold around and integrate with the human body. These wing suits will unfurl and spiraled around the body will allow for human flapping flight.
And add energy storing gyroscopes at the joints.
And design the whole thing adaptively so that there are no hard breaks but only incremental density, strength and shape fading.-- JesusHChrist, Nov 19 2016random, halfbakery
