논문초록 Advances in soft bioelectronics for cardiac implants have been paid remarkable attention to make stable tissue-device interfaces. However, the rigid-island form factors cannot perfectly match the tissue deformations on the heart. To overcome this issue, an alternative approach is to use intrinsically stretchable materials. However, this platform remains challenges due to instability of adhesion, non-uniform coverage on the curved tissue, and the breakdown of the fatigue-accumulated electrodes. Here, we report an instantaneous and conformable cardiac patch with three layers: a tissue-adhesive hydrogel, a network-type substrate, and a durable composite electrode. The patch quickly adheres to the curved tissue according to an efficient strain adaptation of the polymer. Also, its fatigue-resistance enables an electrical stability under a continuous heartbeat. Lastly, the patch provides precise electrical stimulation and 4-week measurement of ECG signals without tissue-pressure.
