Mechanically switchable polymer fibers for sensing in biological conditions [PDF]

open access: yes, 2016
The area of in vivo sensing using optical fibers commonly uses materials such as silica and polymethyl methacrylate, both of which possess much higher modulus than human tissue. The mechanical mismatch between materials and living tissue has been seen to
