提出了一种基于摩擦发电机原理的实用自供电速度传感器，用于整流线性或旋转运动。这项工作代表了将摩擦发电机集成到用于双模式速度传感的商用数字电路中的首次成功尝试。采用交替布置的 Kapton 铜带，以螺旋结构缠绕在两个同心圆柱体的内表面和外表面上，无需外部电源即可测量线性和旋转运动的电压测定。当与数字电路和微控制器单元集成时，摩擦电产生的输出信号可以直接处理成非常稳定的宏观输出信号，用于测量线性速度的 (0.1-0.6) ms(-1)+0.5% 和旋转速度的 (300-700) rpm+0.9%。我们还在本文中讨论了我们设备的测量灵敏度和局限性。我们相信，我们对应用摩擦电技术的开创性演示将对自供电设备和传感器的工业商业化产生巨大影响。 (C) 2014 Elsevier Ltd. 保留所有权利。
A practical self-powered velocity sensor based on the principles of a triboelectric generator for either rectified linear or rotary motion is presented. The effort represents the first successful attempt in integrating a triboelectric generator into a commercial digital circuit for the dual-mode speed sensing. Employing alternating Kapton-copper strips arranged in a spiral configuration wrapped on the inner and outer surfaces of two concentric cylinders, voltage assays for linear and rotary motions can be measured without the need for an external power source. The triboelectric generated output signals when integrated with a digital circuit and a microcontroller unit can be directly processed into remarkably stable, macro-scale output signals for measurements of (0.1-0.6) ms(-1)+0.5% for linear velocities and (300-700) rpm+0.9% for rotary velocities. We have also discussed the measuring sensitivities and limitations of our device in the paper. We believe our pioneering demonstration of the applied triboelectric technology will have a huge impact in the industrial commercialization of self-powered devices and sensors. (C) 2014 Elsevier Ltd.
