我们最近报道，结合正负磁致伸缩板 [Fe-Co 合金和镍 (Fe-Co/Ni) 复合板] 可产生卓越的能量收集和质量传感器性能。因此，在本研究中，将具有比 Ni 更高的负磁致伸缩性能的 CoFe2O4 溅射到 Fe-Co 合金板上。 CoFe2O4 溅射 Fe-Co 合金板比 Fe-Co/Ni 复合板具有更高的能量收集和质量传感器性能。此外，CoFe2O4溅射的Fe-Co合金板成功地将电信号传输到接收器，并且CoFe2O4溅射的Fe-Co合金板的输出电压因微克级二氧化硅颗粒的粘附而发生显着变化。 CoFe2O4溅镀的Fe-Co合金板作为自供电质量传感器具有相当大的价值，这对于无电池病毒传感器的开发可能具有重要意义。
We recently reported that combining positive and negative magnetostrictive plates [Fe–Co alloy and nickel (Fe–Co/Ni) clad plates] yields remarkable energy-harvesting and mass sensor performances. Therefore, in this study, CoFe2O4, which has higher negative magnetostrictive properties than Ni, was spattered onto a Fe–Co alloy plate. The CoFe2O4-spattered Fe–Co alloy plate provided higher energy-harvesting and mass sensor performances than the Fe–Co/Ni clad plate. Moreover, the CoFe2O4-spattered Fe–Co alloy plate successfully transmitted the electrical signal to the receiver, and the output voltage of the CoFe2O4-spattered Fe–Co alloy plate was significantly changed by the adhesion of microgram silica particles. The CoFe2O4-spattered Fe–Co alloy plate has a considerable value as a self-powered mass sensor, which may be significant for the development of battery-free virus sensors.
