AI Technical Summary

Problems solved by technology

[0003] (1) The working characteristics and output characteristics of different types of MEMS micro-energy sources are very different, so special circuits are required to adjust them before compounding

[0004] (2) MEMS micro-fuel cells will generate a lot of heat during the working process, which not only affects the performance of the micro-fuel cells themselves, but also has an unnecessary impact on the entire composite system

[0006] (4) The output of the traditional portable power module is fixed, which is not conducive to the multiple reuse of the same power module, so it is necessary to design a low-power circuit to achieve multiple standard voltage outputs

[0007] (5) The traditional power module will cause harm to the environment, and there is no recycling
