Mechanics modeling, fabrication, and reliability of a printed biosensor for a catheter‐based deployment in a target vessel. A) Design of a highly stretchable sensor via finite element modeling and comparison with the fabricated sensor. B,C) Measured electrical resistance of the printed sensor under a cyclic bending and radial stretching, showing negligible change of resistance under both loading conditions. D) Catheter‐based deployment of the fabricated sensor in a target blood vessel, enabled by the highly flexible and stretchable structure.
