在将技术持续整合到生物体中方面取得进展需要具有生物相容性、机械兼容性并能够利用生物系统内可用的化学能的电源。传统电池的设计并没有考虑到这些标准。然而，刀鱼Electrophorus electricus的电器官是在生物约束下操作的电源的示例，同时具有包括600 V的峰值电势差和1 A的电流的功率特性。在这里，我们介绍了一个鳗鱼启发的电源概念，采用离子梯度跨越微型水凝胶隔室的阳离子和阴离子选择性水凝胶膜的重复序列的边界。该系统采用可扩展的堆叠或折叠几何结构，在数千个串联凝胶隔室的同时自记录机械接触激活时，每个凝胶电池产生110 V或27 mW/m2;这种设计还避免了接触前的功耗。与典型的电池不同，这些系统柔软、灵活、透明，并且具有潜在的生物相容性。这些特性使得人工电子器官在生物和非生物系统的混合体中为下一代植入材料提供动力。
Progress towards continued integration of technology into living organisms requires electrical power sources that are biocompatible, mechanically compliant, and able to harness the chemical energy available inside biological systems. Conventional batteries were not designed with these criteria in mind. The electric organ of the knifefish Electrophorus electricus is, however, an example of an electrical power source that operates within biological constraints while featuring power characteristics that include peak potential differences of 600 V and currents of 1 A. Here, we introduce an eel-inspired power concept that employs gradients of ions across miniature hydrogel compartments bounded by a repeating sequence of cation- and anion-selective hydrogel membranes. The system employs a scalable stacking or folding geometry that generates 110 V or 27 mW/m2 per gel cell upon simultaneous, self-registered mechanical contact activation of thousands of gel compartments in series; this design also circumvents power dissipation before contact. Unlike typical batteries, these systems are soft, flexible, transparent, and potentially biocompatible. These characteristics make artificial electric organs compelling for powering next generation implant materials in hybrids of living and nonliving systems.
