Flexible sensor array has attracted widespread attention and brought many opportunities in future applications, such as electronic skin, human–machine interactions, and healthcare monitoring. In this study, we report the flexible triboelectric sensor array (TSA) with cross bar configurated sensing units for human-machine interaction. Bead-on-string sacrificial structure is fabricated by 3D printing directly and optimized based on experimental and numerical studies, and therefore affords excellent performance in constructing the enhanced electrode lines for TSA. With the especially patterning design and optimization, the number of data channels in TSA is reduced, and high output performance can be achieved effectively. Meanwhile, TSA platform exhibits excellent durability, reliability, waterproofness, and presents the ability in real-time sensing and locating of keystroke position and trajectory tracking. For application scenarios, a TSA-based intelligent digital controller is established for importer identification based on temporal perceiver network. We use this controller in robot manipulation to control gestures of both rigid manipulator and soft pneumatic actuator conveniently. The proposed TSA in this work opens a new route in promising applications in security identification, robot manipulation and artificial intelligence.

基于 3D 打印串珠牺牲层的柔性摩擦电传感器阵列，用于人机交互


柔性传感器阵列引起了广泛的关注，并为未来的应用带来了许多机会，例如电子皮肤、人机交互、医疗保健监控等。在这项研究中，我们报告了具有用于人机交互的横杆配置传感单元的柔性摩擦电传感器阵列（TSA）。串珠牺牲结构直接通过3D打印制造，并基于实验和数值研究进行优化，因此在构建TSA增强电极线方面具有优异的性能。通过特别的图形设计和优化，减少了TSA中的数据通道数量，并且可以有效地实现高输出性能。同时，TSA平台表现出优异的耐用性、可靠性、防水性，并具有实时感知和定位击键位置和轨迹跟踪的能力。针对应用场景，建立了基于TSA的智能数字控制器，用于基于时间感知器网络的进口商识别。我们在机器人操纵中使用该控制器来方便地控制刚性机械臂和软气动执行器的手势。这项工作中提出的 TSA 为安全识别、机器人操作和人工智能等有前景的应用开辟了一条新途径。
