中文摘要:

柔性混合电路(FHC)是将刚性电子元件集成到有印刷电子的柔性基板上形成的一种复合电路。为了满足日趋复杂的应用场景,FHC 上需要集成更多刚性功能电子元件,而这会导致其柔性急剧下降。为了缓解 FHC 在高集成度与高柔性之间的矛盾,本文从结构改进的角度出发,借助镂空蛇形导线岛-桥结构(HS-SWI-BS)对 FHC 进行柔性优化设计。通过三维有限元仿真实验开展了对该方法在有效性和可行性方面的验证,其结果表明,镂空蛇形导线岛-桥结构能够实现 FHC 柔性的提升,且对模型的柔性的提升幅度可达 260%。在柔性经皮电刺激电路上的应用与测试则证明了该方法具有良好的实用性。研究对提高 FHC 的柔性具有参考作用。

英文摘要:

Flexible hybrid circuit (FHC) is a composite circuit formed by integrating rigid electronic components onto a flexible substrate with printed electronics. In order to meet the increasingly complex application scenarios, FHC needs to integrate more rigid functional electronic components, which will lead to a sharp decrease in its flexibility. In order to alleviate the contradiction between high integration and high flexibility of FHC, this article starts from the perspective of structural improvement, which uses a hollow snakeshaped wire island-bridge structure (HS-SWI-BS) to carry out the optimization approach of FHC. The effectiveness and feasibility of this method are verified by three-dimensional finite element simulation experiments. The results show that the hollow snake-shaped wire island-bridge structure can improve the flexibility of FHC, and the increase of the flexibility of the model can reach 260%. The application and testing of flexible percutaneous electrical stimulation circuit have proved that this method has good practicality. The research has a reference role in improving the flexibility of FHC.
