| 摘 要： | 内共振可以加强压电能量采集器.忽略电量的耦合,导出了内共振条件的解析表达式,与考虑电量耦合的精确情形相比,误差很小.数值计算输出电压的均方根表明,用该方法设计的内共振压电能量采集器在Gauss白噪声、2阶滤波产生的色噪声、窄带色噪声和指数相关色噪声激励下,都有良好的性能.

| Abstract: | Internal resonance can enhance piezoelectric energy harvesting. The explicit expression of internal resonance condition was derived via neglecting electric coupling. Compared with the exact vales with the account for the coupling, the errors were small. Numerical calculations of averaged root-mean-square output voltages revealed that the piezoelectric energy harvester design via the approach performed well stimulated by the Gaussian white noise, the colored noise defined by a second-order filter, the narrow-band noise, and exponentially correlated noise. |
