As a domestic waste in daily life, eggshell membrane (ESM) is a unique biomaterial due to its biocompatibility, bioadsorption, and the structure of interwoven and coalescing fibers with many pores which can be utilized in many fields. Herein, a new kind of potentially biocompatible energy harvesting and storage device based on polymer polyaniline/carbon nanotube (PANI/CNT) composite electrodes and ESM is designed. Without external electric power, a single device can extract a maximal output voltage of 0.26 V from water osmosis. The energy can be stored directly and released circularly, and the output voltage can achieve superposition by integrating devices in series. This self‐charging bioelectric phenomenon can be explained by the membrane potential of the ESM induced by water movement. Due to the biocompatible feature of the ESM, and sufficiently high electric output, this study provides a new idea for sustainable and biocompatible energy harvesting and storage devices.

卵壳膜透水的能量收集和存储

作为日常生活中的生活垃圾，蛋壳膜（ESM）由于其生物相容性，生物吸附性以及具有许多孔的交织和聚结纤维的结构而成为一种独特的生物材料，可在许多领域中使用。本文设计了一种基于聚合物聚苯胺/碳纳米管（PANI / CNT）复合电极和ESM的潜在生物相容的能量采集和存储装置。无需外部电源，单个设备即可从水渗透中提取最大0.26 V的输出电压。能量可以直接存储并循环释放，并且通过串联集成器件可以实现输出电压的叠加。这种自充电的生物电现象可以用水运动引起的ESM的膜电位来解释。由于ESM具有生物相容性，
