A self-powered vibration sensor based on electromagnetic induction is presented in this paper. The vibration sensor is implemented with stacked flexible coils and polymeric springs. The stacked flexible coil enables large output signal, while long and flexible springs enable high sensitivity and wide linear range of the sensor. At resonance, the sensor has a sensitivity of 1.83 V/g and a maximum resolution of 0.002 g. In the high-frequency range, where the sensor output is frequency-independent (100–3000 Hz), the sensor has a sensitivity of 66.5 mV/g, a maximum resolution of 0.05 g, and a measurement range up to 8.5 g.

一种宽带宽自供电振动传感器

本文提出了一种基于电磁感应的自供电振动传感器。振动传感器由堆叠的柔性线圈和聚合物弹簧实现。堆叠的柔性线圈可实现大输出信号,而长而灵活的弹簧可实现传感器的高灵敏度和宽线性范围。在谐振时,传感器的灵敏度为 1.83 V/g,最大分辨率为 0.002 g。在高频范围内,传感器输出与频率无关(100–3000 Hz),传感器的灵敏度为 66.5 mV/g,最大分辨率为 0.05 g,测量范围高达 8.5 g。
