研制了锌/铂（Zn/Pt）永磁微电机。它们的移动基于燃料化合物如溴、对苯醌和甲醇在Pt表面的还原和同时发生的Zn的氧化（溶解）。Zn ~（2+）/Zn的氧化还原电位很负，有利于发生氧化还原反应。研究了电机的运动和表面上发生的反应。对于含有Ni的测试马达，揭示了Zn/Pt马达显示出几乎向Zn侧的单向运动。Zn ~（2+）的毒性相对较低。此外，电动机的特点是使用温和的化合物，如甲醇，是无害的组织或生物体作为其燃料。
Zinc/platinum (Zn/Pt) bimetallic micromotors have been developed. They moved based on the reduction of fuel compounds such as bromine, p-benzoquinone, and methanol at the surface of the Pt and the oxidation (dissolution) of Zn that occur simultaneously. The redox potential of Zn2+/Zn is very negative and was advantageous to cause the redox reactions. The motion of the motor and the reactions that occurred on the surface were investigated. With test motors containing Ni, it was revealed that the Zn/Pt motors showed almost unidirectional motion to the Zn side. Toxicity of Zn2+ is relatively lower than that of other metal ions. Also, the motor features the use of mild compounds such as methanol that are not harmful to tissues or organisms as their fuels.
