A flexural actuator is fitted with an actuator means, the flexural actuator being fitted at its functional section with a sensor means for determination of the longitudinal stretch. This sensor means is placed at a position, and/or is placed in the longitudinal direction symmetrically on either side of such position, at which there is a constant longitudinal stretch independent from the setting force when the functional section is thrusting against a resistance.

A microstructure relay is provided, having a body that includes upper and lower portions. The lower portion is formed from a substrate, and the upper portion is formed on the substrate to avoid bonding of the lower portion to the upper portion. A support member is fixed to the body at a first end of the support member to form a cantilever, wherein an upper surface of the support member and a lower surface of the upper portion of the body form a cavity. A first contact region is located on the upper surface at a second end of the support member. The first contact region comprises a first contact, wherein pivoting the support member toward the lower surface causes the first contact to be electrically coupled to a counter contact.

Micro-relay

The invention relates to a relay, especially a miniaturized electrostatic relay, comprising a bridge-type make contact. The contact spring is designed as a torsion spring that is linked with a switching spring ( ) via multiply bent spring parts ( ). It is thus possible in particular to compensate fixed contacts ( ) of different heights. The invention further relates to a method for producing the relay as a micro-mechanical electrostatic relay.

Microelectromechanic relay and method for the production thereof

An apparatus and method for a micromechanical electrostatic relay that includes a base substrate and a carrier layer deposited onto the base substrate. The carrier layer includes an armature and stationary-contact spring tongues that engage each other at their respective free ends. Once engaged, the armature spring tongue moving contacts overlaps the respective stationary-contact spring tongue stationary contacts. During an electrostatic rest state, the armature and stationary-contact spring tongues curve away from the base substrate wherein their respective free ends no longer engage.

The micromechanical electrostatic relay has, on the one hand, a base substrate with base electrode and a base contact piece and, on the other hand, an armature substrate with an armature spring tongue that is etched free and curved away from the base substrate, and that has an armature electrode and an armature contact piece. When a control voltage is applied between the two electrodes, the spring tongue unrolls on the base substrate until it is stretched and causes the two contact pieces to touch. In order to obtain a high contacting force given an optimally large electrode area, the armature contact piece is arranged on a contact spring section that is cut free from the spring tongue via spring webs in the form of a sun wheel with spoke sections helically interengaging such that it is surrounded on all sides by the spring tongue.

Micromechanical relay

Micromechanical relay having a hybrid drive

A micromechanical electrostatic relay has a base substrate with a base electrode and a base contact piece. The relay also has an armature substrate with an armature spring tongue that curves away from the base substrate, and an armature electrode and an armature contact piece. When a control voltage is applied between the two electrodes, the spring tongue unrolls on the base substrate and thus closes the contact. The curvature of the spring tongue in the quiescent condition is produced by a coating with a compressive strain layer. In order to avoid undesired transverse arcs of the spring tongue, the compressive strain layer is subdivided into strips by slots in a longitudinal direction of the spring tongue. A tensile stress layer applied in surface-wide fashion over the strips and slots reinforces the compensation effect.

Micromechanical relay with transverse slots

A micromechanical electrostatic relay has, on the one hand, a base substrate with a base electrode and a base contact piece and, on the other hand, an armature substrate with an armature spring tongue that is etched free and curved away from the base substrate and that has an armature contact piece. When a control voltage is present between the two electrodes, the spring tongue unrolls on the base substrate until it is stretched and causes the two contact pieces to touch. In order to prevent a creeping contacting and make the closing and opening of the contact abrupt, a geometric discontinuity is provided in the wedge-shaped air gap between the two electrodes. This discontinuity is formed by a partially curved, partially straight design of the spring tongue, by an offset of the beginning of the electrode relative to the spring attachment, and/or by an air gap between the spring attachment and the base electrode. The result is an unambiguous switching hysteresis with trip events when closing and opening the contact.

Detachable multiple splicing connector for light waveguides

A device for deflecting light through 180.degree. characterized by a directional coupler comprising a pair of strip waveguides formed on a substrate with the end faces of the pair of strip waveguides being provided with a mirror. The directional coupler may be formed as a half of a coupler with the mirror effectively bisecting the length of the coupler, or it may be a .DELTA..beta. reversible directional coupler which is the whole length or as a half of a directional coupler. In addition, the directional coupler may be a controllable power dividing coupler and a phase shifter may be applied on one of the waveguides of the coupler. The device can also be utilized in a spectral comb filter.
