The facile and rapid fabrication of oriented porous polymers is crucial for flexible pressure sensors. Herein, a pressure sensor is developed based on oriented porous polydimethylsiloxane (PDMS) composites for detecting human motion and identifying joint motion patterns. The oriented porous PDMS composite is first constructed through thiol-ene click chemistry and directional freezing within only 30 min, then fabricated by interfacial in situ polymerization of dopamine and pyrrole to generate robust interfaces. As a result, the as-prepared oriented porous PDMS composite is assembled into a pressure sensor that shows potential applications in pressure and human motion detection. Interestingly, a sensor assembled by orthogonally stacking the PDMS composites can be used for joint motion pattern recognition with potential monitoring of football motion due to their directional structures. This facile strategy coupled with the oriented porous structure is expected to help design advanced wearable electronic devices.

制造用于运动监测和识别运动模式的定向多孔 PDMS 复合材料的简便方法

定向多孔聚合物的简便快速制造对于柔性压力传感器至关重要。在此，基于定向多孔聚二甲基硅氧烷 (PDMS) 复合材料开发了一种压力传感器，用于检测人体运动和识别关节运动模式。定向多孔 PDMS 复合材料首先通过硫醇-烯点击化学和定向冷冻在 30 分钟内构建，然后通过多巴胺和吡咯的界面原位聚合制备，以产生坚固的界面。因此，所制备的定向多孔 PDMS 复合材料被组装成压力传感器，显示出在压力和人体运动检测中的潜在应用。有趣的是，通过正交堆叠 PDMS 复合材料组装的传感器可用于联合运动模式识别，并由于其定向结构而可能监测足球运动。这种简便的策略与定向多孔结构相结合，有望帮助设计先进的可穿戴电子设备。
