Svv/(R*Saa)μW/mm³/g² 形式归一化,这和你想用输入加速度强度归一化功率的思路一致。对你的论文/报告,建议这样定位:
P(f),即 P(t)=Vrms(t)^2/R,再用已知 f(t) 映射到频率。PSD-based spectral power distribution 或 input-normalized spectral power metric,用于说明输出能量在频域中的分布。可用英文表述:
Frequency-sweep tests were used to characterize the broadband harvesting performance, while PSD-based spectral power analysis was used as a complementary frequency-domain energy metric. [1][3][6][7] Since the sweep excitation was treated as a nonstationary test condition in this analysis, the PSD-based result was interpreted as a spectral power distribution rather than a strict steady-state power-frequency response.
