This paper introduces sponge-like poroelastic silicone composites for high-precision direct writing of custom-designed stretchable biosensors. These biosensors are soft, insensitive to strains, and robustly couple to living tissues, enabling high-fidelity recording of electrophysiological activity and real-time ultrasound imaging. In vivo evaluations in a murine acute myocardial infarction model demonstrate their potential for simultaneous intraoperative recording and imaging on the epicardium.
