real-time measurement of drill string vibration during the drilling process is crucial for drilling operations and downhole safety. However, the traditional power supply mode for downhole vibration sensors increases drilling costs and reduces drilling efficiency. Sensors with self-powered capabilities are undoubtedly more suitable for practical conditions. Based on the principle of triboelectric nanogenerator, this study proposes a downhole arrayed self-powered deformable vibration sensor. Experiments show that the sensor can synchronize measurements of amplitude and frequency, with a vibration frequency measurement range of 0 to 11 Hz and a measurement error of less than ±4%. It can also measure three discrete amplitude values (10 mm, 25 mm, and 40 mm) with a measurement error of ±3 mm. In addition, the sensor has power generation capabilities, with experiments showing a maximum output power of 8.3×10-7 W. Furthermore, when multiple sensors are used in parallel, the power generation capacity is significantly enhanced. The research findings can provide new insights for the development of downhole sensors and downhole generators.
