    • 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.

    • A foil moveable by non-mechanical means, such as light or heat, comprises an alternating array of first and second foil sections each resiliently and non-mechanically moveable between a flattened state and a bent state. The direction in which the first foil sections bend, when moved from the flattened to the bent state, is opposite to the direction in which the second foil sections bend when moved from the flattened to the bent state. When, in the flattened state, non-mechanically stimulating the first and second foil sections in unison, the first and second foil sections bend in opposite directions causing the foil to wrinkle, which results in a movement which is substantially linear. Using a different or removing the non-mechanical stimulus, the foil sections can be made to unbend resulting in a flattening and expansion of the foil to its original shape.
    • 可通过诸如光或热的非机械装置移动的箔包括第一和第二箔片段的交替阵列,每个片状部分在扁平状态和弯曲状态之间弹性地且不可机械地移动。 当从扁平状态移动到弯曲状态时,第一箔片部分弯曲的方向与第二箔片部分从扁平状态移动到弯曲状态时弯曲的方向相反。 当处于扁平状态时,第一和第二箔部分一致地非机械地刺激第一和第二箔片部分,第一和第二箔片部分在相反的方向弯曲,导致箔片起皱纹,这导致基本上线性的移动。 使用不同的或去除非机械刺激,箔片部分可以制成不弯曲,导致箔的平坦化和膨胀到其原始形状。
