基于接触分离模式纳米发电机的传感器（CS-NGS）凭借自供电、高灵敏度、结构简单和低成本等优点而备受关注。为了设计更好的CS-NGS以供实际应用，本工作对CS-NGS的传感器特性进行了系统分析。针对具有不同输出信号（例如开路电压、短路转移电荷、短路电流和负载电压）的 CS-NGS，分析了传感器特性，包括频率响应、灵敏度、线性度和失真。还讨论了结构参数和工作条件对这些性能的影响。对CS-NGS在三种典型应用场景下进行了仿真实验，结果表明Delta Q(SC)型、I-SC型和V-L型CS-NGS都有各自适合的应用领域。全面比较了不同输出类型CS-NGS之间的性能。这项工作对 CS-NGS 的传感器特性进行了系统的解释，并为特定应用的 CS-NGS 的设计和优化提供了指导。
Contact-separation mode nanogenerator-based sensors (CS-NGSs) have attracted much attention by taking advantage of self-powering, high-sensitivity, simple structure, and low cost. To design a better CS-NGS for practical application, a systematic analysis of the sensor properties for CS-NGSs was implemented in this work. The sensor properties including frequency response, sensitivity, linearity, and distortion were analyzed for CS-NGSs with different output signals such as open-circuit voltage, short-circuit transferred charge, short-circuit current, and load voltage. The influence of the structure parameters and the working conditions on these properties were discussed too. Simulation experiments were conducted for CS-NGSs under three typical application scenarios, and the results indicate that the Delta Q(SC)-type, the I-SC-type, and the V-L-type CS-NGSs have their own suitable application areas. The properties between the different output-type CS-NGSs are comprehensively compared. This work presents a systematic interpretation of the sensor properties of CS-NGSs and provides guidance for the design and optimization of CS-NGSs for specific applications.
