转速传感器对于现代工业自动化的发展至关重要。可靠性、集成性、测量范围和精度是其应用的关键特性。我们报道了一种摩擦电转速传感器，它集成在一个轴承中（TRSS），主要由轴承座、轴承、调节环、转子和定子组成。通过改变轴承的结构特性，可以显著提高传感器输出的稳定性。通过转子上的铜光栅与定子表面的聚四氟乙烯薄膜之间的旋转摩擦产生周期性电信号，从而在铜电极上诱导电子转移。将输出信号分析与商用传感器进行比较证明，TRSS可用于测量10 - 1000转/分钟的转速，误差低于0.3%，且线性度良好。因此，通过验证不同尺寸传感器的测量精度，表明TRSS是可靠且稳定的。我们将这种传感器应用于工业领域，并展示了TRSS的应用前景。（C）2019爱思唯尔有限公司。保留所有权利。
A rotational speed sensor is of great importance for the development of modern industrial automation. The reliability, integration, measuring range and accuracy are key characteristics to its application. We report a triboelectric rotational speed sensor that is integrated into a bearing (TRSS) and is composed mainly of a bearing seat, a bearing, an adjusting ring, a rotor and a stator. The sensor-output stability can be improved significantly by modifying the bearing's structural characteristics. Periodic electric signals are generated by rotating friction between the copper grating on the rotor and a polytetrafluoroethylene film on the stator surface to induce electron transfer on the copper electrode. A comparison of the analysis of the output signal with a commercial sensor proved that TRSS can be used to measure the rotational speed from 10-1000 rpm with an error below 0.3% and an excellent linearity. Therefore, TRSS is reliable and consistent by verifying the measurement accuracy of the sensors with different sizes. We applied this sensor in an industrial application and demonstrated the application prospects of TRSS. (C) 2019 Elsevier Ltd. All rights reserved.
