Intercellular Ion-Gradient Piezoheterogated Biphasic Gel for Ultrahigh Iontronic Generation

over 24 h can be realized. Meanwhile, we develop piezoionic devices that can interface with paralyzed vagus nerves and successfully regulate the blood pressure of rodents through their neuromodulation. By matching the ion species with heterointerface gating effects to regulate the ionic transmission efficiency, the piezo signal neuromodulation process can be further governed. We anticipate that the bioinspired heterointerface engineering strategy can provide new insights into designing high-performance piezoionic systems for promising abiotic-biotic applications.
