Abstract: A microelectrical device comprising two generally parallel electrodes (20,21) at least one of which is movable, and at least one of the electrodes comprising a layer of a semiconductor presenting space charge characteristics. The electrodes have a closed position an open position. A spring effect biases the movable electrode (21) towards the open position. When the movable electrode (21) is closed by a first voltage pulse (P1) a sufficiently high space charge density (10) is generated to hold the movable electrode (21) closed. When zero voltage is applied the movable electrode (21) is held closed by the built in space charge until the application of a second voltage pulse (P2) which decreases the space charge in the semiconductor (10) to allow the movable electrode(s) to be moved to the open position by the spring effect.

Abstract: An RF MEMS switch having asymmetrical spring rigidity. The RF MEMS switch has supporting members spaced apart in a certain interval on a substrate, a membrane being a motion member suspended by plural spring members extended on both sides of the membrane, and a bottom electrode being a contact surface on an upper surface of the substrate facing a bottom surface of the membrane, wherein the plural spring members placed on opposite sides of the membrane have asymmetrical rigidity, and a portion of the membrane on a side of stronger spring rigidity is first separated from the contact surface when the RF MEMS switch is turned off. The present invention has an advantage of easy separation of the switch from the contact surface, when the switch is turned off, due to the different rigidity of the springs located on the sides of the membrane.

Abstract: The invention relates to an electrostatic microswitch which is intended to connect electrically two strip conductors which are disposed on an insulating support (21), the two strip conductors are connected electrically by conducting means (38) which are provided in the central part of deformable means (28) which can be deformed in relation to the support under the effect of an electrostatic force generated by control electrodes (25, 48; 26, 58). The control electrodes are distributed facing one another on the deformable means and the support, such as to form capacitive means around the aforementioned conducting means. The control electrodes are associated with insulating stop elements (35, 36) which are provided in order to prevent a short circuit between electrodes of the capacitive means during the deformation of the deformable means. The distance between the deformable means and the ends of the strip conductors is less than or equal to the distance between the insulating stop elements associated with the control electrodes and the control electrodes located opposite.

Abstract: A microelectromechanical system includes separate conducting elements. An electromechanically deformable element can be switched between a first stable position and a second stable position. Contact elements allow for electrical continuity to be established between the separate conducting elements. Switch control elements ensure that the first deformable element switches so as to establish electrical continuity between the separate conducting elements in the second stable position, by contact between the contact elements, and to break electrical continuity by separating the contact elements in the first stable position. The separate conducting elements and the contact elements are carried by the deformable element.

Abstract: A bistable structure provided by the invention is characterized as including a deflection element that has mechanically constrained end points and a compliant span between the end points that is substantially free to deflect between two stable positions when a force is applied at a point along the span. The deflection element span is provided, as-fabricated, curved in one of the two stable positions and in a mechanically unstressed condition along the length of the span. The as-fabricated curve of the deflection element span includes a curve maxima at a point along the span length that is at least about ¼ of the span length from the end points of the span. The deflection element span is constrained to substantially prohibit development of a second bending mode that is characteristic for the span as the element deflects between the two stable positions.
