作者在这项研究中介绍了一种新方法的开发,该方法用于从双层柔性印刷电路板(柔性 PCB)创建可拉伸电子器件,作为用于心脏电压映射应用的软机器人传感器阵列(SRSA)的平台。迫切需要利用多个传感器并为心脏绘图提供高性能信号采集的设备。此前,我们的团队演示了如何对单层柔性 PCB 进行后处理以创建可拉伸的电子传感阵列。在这项工作中,介绍了创建双层多电极柔性 PCB SRSA 的详细制造工艺,以及使用激光切割机实现最佳后处理的相关参数。双层柔性 PCB SRSA 采集电信号的能力在体外和体内的 Leporine 心脏表面上得到了证明。这些 SRSA 可以扩展到全腔心脏标测导管应用。我们的结果表明,双层柔性 PCB 对可拉伸电子产品的可扩展使用做出了重大贡献。
The authors present in this study the development of a novel method for creating stretchable electronics from dual-layer flex printed circuit boards (flex-PCBs) as a platform for soft robotic sensor arrays (SRSAs) for cardiac voltage mapping applications. There is a crucial need for devices that utilize multiple sensors and provide high performance signal acquisition for cardiac mapping. Previously, our group demonstrated how single-layer flex-PCB can be postprocessed to create a stretchable electronic sensing array. In this work, a detailed fabrication process for creating a dual-layer multielectrode flex-PCB SRSA is presented, along with relevant parameters to achieve optimal postprocessing with a laser cutter. The dual-layer flex-PCB SRSA’s ability to acquire electrical signals is demonstrated both in vitro as well as in vivo on a Leporine cardiac surface. These SRSAs could be extended into full-chamber cardiac mapping catheter applications. Our results show a significant contribution towards the scalable use of dual-layer flex-PCB for stretchable electronics.
