Disclosed is to a device for exchanging minimum amount of the fluid only by using surface tension of the fluid instead of external force like a pump. According to the device, an additional pump and power supply is not needed, thereby the device can be small sized and portable, and not only manufacturing cost decreases and yield increases but the device is hardly out of order.

Device for controlling fluid using surface tension

A microfluidic device for controlling the flow of a micro amount of fluid is provided. The microfluidic device is manufactured by binding a sensing substrate including a sensing electrode, an electrode interconnect, and a electrode pad, with a channel substrate including at least two fluid inlet ports, a chamber, and a channel, wherein a first fluid injected via one of the fluid inlet ports flows by natural capillary force, and a second fluid injected via another fluid inlet port is forced to flow by an external pump. The microfluidic device controls fluid flow and flow stoppage by a combination of natural capillary flow and an externally applied pressure as a result of the action of a pump.

Microfluidic device for the controlled movement of fluid

The present invention relates to a micro-electromechanical actuator. An electromagnetic-type micro-electromechanical actuator of the present invention has a conductive beam formed in a micro electronic substrate on an upper side of a magnetic substance, so that the conductive beam can be moved toward an in-plane mode in parallel to the micro electronic substrate depending on a direction that current flows. Therefore, the micro-electromechanical actuator can be applied to most of electromagnetic micro-electromechanical systems that require an in-plane mode.
