In nature, electricity-generating fishes such as eels and rajas can efficiently convert biological energy into electric energy and instantly release 10-800V high voltage, and the principle is as follows: hundreds of power generating cells are distributed in the power generating organ of the electric eel, when being stimulated, Na + channels on the front membrane of the power generating cells are opened, K + channels are closed, so that Na + flows into the cells across the front membrane of the cells, K + flows out of the cells across the back membrane of the cells, and each power generating cell can generate about 150mV voltage by means of ion transmembrane transport. Under the regulation and control of a nervous system, the electricity generating cells 'battery units' in the electricity generating organ can be orderly, directionally and serially arranged, so that the high-efficiency output of biological electric energy is realized.
The fish power generation mechanism of the simulated power generation opens up a new direction for the design and manufacturing method for exploring biological energy.

Four gel battery particle arrays are sequentially printed on a polyvinyl chloride film of a multi-nozzle dispenser and assembled in sequence to generate potential difference, and the maximum 110V open-circuit voltage can be generated by connecting thousands of gel battery units in series. The 3D printing method can be used for realizing accurate manufacturing of the tiny gel battery particles, but the time consumption of large-scale manufacturing is long, each battery material is printed in sequence in the manufacturing process, the printed liquid drop liquid volume is smaller than the design liquid volume to different degrees due to the fact that the printed gel battery particles are dehydrated in the air due to long manufacturing time, manufacturing precision is affected, the manufacturing process is not controllable, and large-scale manufacturing efficiency is limited.
