Abstract In the era of industry 4.0, mechanical indicators are in great demand for providing reliable information in a harsh environment with a self-powered signal transmission ability for connecting into a centralized automatic control network of ships, trucks, and factories. In this work, based on the principle of nanogenerator, we report a block-inserting mechatronic (BIM) panel employed as not only a mechanical indicator with long operation lifetime, versatile adaptability, and improved reliability under harsh working conditions, but also an active electronic sensor for self-powered liquid information indicating and sensing. The methodology of block-inserting assembly significantly simplifies the processing costs and difficulties, which facilitates length-customization of the whole device. When equipped with the BIM panel, computer control and monitoring systems realize wireless control and real-time monitoring of liquids in miscellaneous industrial applications. This work lays the foundation of nanogenerator-based sensors applied in industrial systems, which will strongly promote the progress of industry 4.0, smart cities, and transportation.

用于智能制造和安全运输的自供电液体传感的可靠机电一体化指示器

摘要 在工业4.0时代，机械指标迫切需要在恶劣的环境中提供可靠的信息，并具有自供电的信号传输能力，以连接到船舶、卡车和工厂的集中自动控制网络。在这项工作中，基于纳米发电机的原理，我们报告了一种嵌块机电（BIM）面板，它不仅是一种具有长使用寿命、通用适应性和在恶劣工作条件下提高可靠性的机械指示器，而且还是一种有源电子用于自供电液体信息指示和传感的传感器。嵌块组装的方法大大简化了加工成本和难度，有利于整个设备的长度定制。配备BIM面板时，计算机控制和监控系统实现了各种工业应用中液体的无线控制和实时监控。这项工作为基于纳米发电机的传感器应用于工业系统奠定了基础，将有力推动工业4.0、智慧城市和交通的进步。
