Measurement while drilling (MWD) system of offshore drill pipe is of great significance for safety production. It is greatly demanded to develop a sustainable power supply as well as self-powered sensors for the MWD system. In this work, a drill pipe-embedded annular type triboelectric nanogenerator (AT-TENG) is proposed and systematically investigated, and it consists of an annular silicone rubber and a pair of electrodes. The design of the AT-TENG allows the silicone rubber to contact and separate with the electrodes easily in a narrow space under arbitrary direction vibration to realize power generation. The experimental results show that the peak power density of AT-TENG with single-pair electrode reaches 63.7 W m⁻³ under the vibration frequency of 4 Hz and amplitude of 100 mm. The minimum peak voltage is >65 V within 360° lateral vibration range. The peak voltage achieves 351.62 V under the third-order natural frequency. In addition, the amplitude and frequency obtained from the voltage signals exhibit linearly with those of actual vibration. The mean error between the frequency detected by AT-TENG and actual frequency is <0.03%. Thus, the AT-TENG can serve as an energy harvester and self-powered vibration sensor.

基于环形摩擦纳米发电机的钻杆嵌入式振动能量收集器和自供电传感器随钻测量系统

海洋钻杆随钻测量（MWD）系统对安全生产具有重要意义。迫切需要为 MWD 系统开发可持续的电源和自供电传感器。在这项工作中，提出并系统地研究了一种嵌入钻杆的环形摩擦纳米发电机（AT-TENG），它由环形硅橡胶和一对电极组成。AT-TENG的设计使得硅橡胶可以在任意方向振动的狭窄空间内轻松地与电极接触和分离，从而实现发电。实验结果表明，单对电极AT-TENG的峰值功率密度在4 Hz和100 mm的振动频率下达到63.7 W m ^{-3 。}最小峰值电压为> 65 V 在 360 °横向振动范围内。在三阶固有频率下，峰值电压达到 351.62 V。此外，从电压信号获得的幅度和频率与实际振动的幅度和频率呈线性关系。AT-TENG 检测到的频率与实际频率之间的平均误差< 0.03%。因此，AT-TENG 可以用作能量收集器和自供电振动传感器。
