Micromotors convert energy from their surroundings into mechanical motion, enabling them to perform various tasks, such as cargo delivery, biosensing, and environmental remediation. Multi-drive micromotors are highly desirable since they can utilize more energy and harness a wider range of energy forms, benefiting the precise motion control and the practical applications. Herein, we report a simple method to fabricate dual-drive hybrid PS@Fe3O4@Pt-PS micromotor by swelling and selective surface modification of polymeric colloids. The micromotors are powered by two energy sources, chemical reaction and magnetic field. The well-controlled motions of such hybrid micromotors are demonstrated.

通过聚合物胶体的溶胀和选择性表面改性制备双驱动混合微电机

微型电动机将周围环境中的能量转换为机械运动,从而使其能够执行各种任务,例如货物运输,生物传感和环境修复。由于多驱动微电机可以利用更多的能量并利用更大范围的能量形式,因此非常受人们青睐,这有利于精确的运动控制和实际应用。在这里,我们报告了一种简单的方法,通过聚合物胶体的溶胀和选择性表面改性来制造双驱动混合PS @ Fe 3 O 4 @ Pt-PS微电机。微型马达由两种能源供电,即化学反应和磁场。这种混合微电机的运动得到了很好的控制。
