    • The present invention provides a micro-fluidic system (100) comprising at least one micro-channel (15). The micro-fluidic system (100) furthermore comprises in the micro-channel (15) a plurality of ciliary actuator elements (10) comprising a host material (11) and at least one component (12) provided to the host material (11), and stimulus application means (16) adapted for applying a combination of at least a first and second stimulus to the plurality of ciliary actuator elements (10). The first stimulus is for actuating one of the host material (11) or one of the at least one component (12), and the second stimulus is for actuating one of the host material or one of the at least one component (12), the first and the second stimuli being for actuating different materials. The present invention also provides a method for manufacturing such a micro-fluidic system (100) and a method for controlling or manipulating a fluid flow through a micro-channel (15) of such a micro-fluidic system (100). The micro-fluidic systems may, for example, be used in biotechno logical and pharmaceutical applications and in micro-channel cooling systems in microelectronics applications. Micro-fluidic systems according to embodiments of the present invention are compact, cheap and easy to process.
    • 本发明提供一种包括至少一个微通道(15)的微流体系统(100)。 微流体系统(100)还在微通道(15)中包括多个包括主体材料(11)的纤维致动器元件(10)和提供给主体材料(11)的至少一个部件(12) 以及刺激施加装置(16),其适于将至少第一和第二刺激的组合应用于所述多个纤毛致动器元件(10)。 第一刺激是用于致动主体材料(11)中的一个或至少一个部件(12)中的一个,并且第二刺激用于致动主体材料之一或至少一个部件(12)中的一个, 第一和第二刺激是用于驱动不同的材料。 本发明还提供了一种用于制造这种微流体系统(100)的方法和用于控制或操纵通过这种微流体系统(100)的微通道(15)的流体流动的方法。 微流体系统可以例如用于生物技术和药物应用以及微电子应用中的微通道冷却系统中。 根据本发明的实施例的微流体系统是紧凑的,便宜的并且易于处理。
