本文提出了一种利用光辐射驱动片上水凝胶微驱动器的方法。所提出的驱动方法使得能够局部加热温度响应性水凝胶致动器。水凝胶驱动器由温度响应凝胶制成，并制作在具有光吸收微图案的微流控芯片上。因此，致动器可以通过在其上照射光来驱动并且增加其温度。这种驱动方法的优点是可以实现致动器的局部加热，减少对衬底和环境的散热。此外，局部加热使得能够将多个致动器放置在短距离中，而不会通过热耗散意外地致动相邻致动器。此外，利用光照射加热不需要在芯片上进行任何布线。因此，本发明的驱动方法能够在芯片上集成大量的水凝胶微致动器并独立驱动，这种大量的芯片上水凝胶微致动器的大规模集成将在微流控芯片上实现高通量和高功能的各种单细胞操作。
In this paper, we present driving method of on-chip hydrogel microactuator by using light irradiation. The presented driving method enables local heating of temperature responsive hydrogel actuator. The hydrogel actuator is made of temperature responsive gel and fabricated on a microfluidic chip with light absorbing micropattern. Thus, the actuators can be driven by irradiating light on it and increase its temperature. The advantage of this driving method is it can achieve local heating of the actuator and reducing heat dissipation to substrate and environment. Furthermore, the local heating enables to put the multiple actuators in short distance without unintended actuation of neighbor actuators by heat dissipation. Additionally, heating with light irradiation does not need any wiring on the chip. Therefore, proposed driving method enables to integrate large number of hydrogel actuators on a chip and independently drive it. This massive integration of large number of on-chip hydrogel microactuators will realize high-throughput and highly functional various single cell manipulations on a microfluidic chip.
