    • A relay device using a conductive fluid and having an excellent switching response is provided. The relay device is formed by bonding a semiconductor substrate to an insulator substrate, and mainly comprises a stacked layer body having an interior space, at least two contact points exposed to the interior space, a diaphragm portion facing the interior space, conductive fluid sealed in the interior space, and an actuator for elastically deforming the diaphragm portion. The diaphragm portion is provided on the semiconductor substrate, so that the drive force of the actuator necessary for elastically deforming the diaphragm portion can be reduced and the volume change of the interior space can be obtained with a fast response. This volume change causes the positional displacement of the conductive fluid in the interior space, thereby forming a conduction state or non-conduction state between the contact points.
    • 提供了使用导电流体并具有优异的切换响应的继电器装置。 中继装置是通过将半导体基板接合到绝缘体基板而形成的,主要包括具有内部空间的叠层体,至少两个暴露于内部空间的接触点,面向内部空间的隔膜部分,密封在 内部空间和用于弹性变形隔膜部分的致动器。 隔膜部分设置在半导体基板上,从而可以减小振动板部分弹性变形所需的致动器的驱动力,并能够以较快的响应获得内部空间的体积变化。 该体积变化导致导电流体在内部空间中的位置偏移,从而在接触点之间形成导通状态或非导通状态。

    • A MEMS(Micro Electro Mechanical Systems) switch is provided to prevent stiction from occurring between contact points by turning the switch on and/or off by using electrostatic and piezoelectric forces. A first contact point(120) is positioned in a predetermined first area on an upper surface of a substrate(110). A support layer(130) is suspended at a predetermined distance from the upper surface of the substrate. A second contact point(140) is formed on a lower surface of the support layer. A first actuator(150) moves the support layer in a predetermined direction by using an electrostatic force. A second actuator(160) moves the support layer in a predetermined direction by using a piezoelectric force. If a predetermined first power source is connected to the first actuator, the first actuator moves the support layer toward the substrate so that the second contact point contacts the first contact point.

    • An electrical relay having two wettable electrical contacts (118 and 120), each supporting a conducting liquid (126). A wettable switch finger (114) is moved from a non-deflected position to first and second positions by action of an actuator (130, 132 or 140). In the first position the switch finger (114) touches the conducting liquid (126) and causes it to wet between the contacts and the switch and thereby complete an electrical circuit between the contacts. When the switch finger (114) is in the second position, the conducting liquid (126) cannot wet between first and second contacts and the switch finger and the electrical circuit between the first and second contacts is broken. The switch finger (114) may be located at the free end of a beam (112) that is deflected or bent by the action of piezoelectric elements (130, 132 or 140).
