博士期间的第一篇SCI是关于电磁型能量采集器的论文，于2011年投稿到Applied Physics Letters上，经过5个多月的审稿和修稿，终于被接受，于2012年5月发表。Congratulations!

Abstract: We proposed a multi-frequency sandwich type vibration energy harvester to widen the effective
frequency range of vibration energy harvester. The harvester is composed of three resonant structures
with different natural frequencies. The resonant structures are two cantilevers each with bi-layer coils
and a plane spring with a magnet. The maximum peak-peak voltages of the three different frequencies
are 172 mV, 104 mV, and 112mV at the frequencies of 235 Hz, 330 Hz, and 430 Hz, respectively.
The first maximum voltage is much higher than the others, because the coils in both cantilevers can
produce voltages.
