Nanocrystalline diamond coatings exhibit stress in nano/micro-electro mechanical systems (MEMS). Doped nanocrstalline diamond coatings exhibit increased stress. A carbide forming metal coating reduces the in-plane stress. In addition, without any metal coating, simply growing UNCD or NCD with thickness in the range of 3-4 micron also reduces in-plane stress significantly. Such coatings can be used in MEMS applications.

Magnetically driven trip mechanism for an overload relay

Номер: US20160126039A1
Автор: Conrad S. Weiden
Принадлежит: Schneider Electric USA Inc

In an overload relay, a tripping actuator 12 has a first magnet 18 and a moveable contact carrier 20 has a second magnet 28 mounted opposed to the first magnet. A moveable contact 22 on the moveable contact carrier is urged by repulsion between the magnets, to make a normally closed connection with a stationary contact 24, when the tripping actuator is in an ON position 15 and the contact carrier in a first stable position 26′. The magnets pass through an over-center tripping position (T) when the tripping actuator is moved to an OFF position 23 in response to an overcurrent condition sensed by a bimetallic thermal overload sensor 16. The magnets repel each other after passing through the over-center tripping position, to thereby urge the moveable contact into a second stable position 26, away from the stationary contact, to break the normally closed connection with the stationary contact.

Single bulk unimorph piezoelectric elements, with interdigitated electrodes aligned obliquely relative to the direction perpendicular to the axis of the element, such that a torsional response is induced into the element. When such elements are used as a beam structure, with angularly oriented electrodes on both opposite surfaces of the beam, and with their orientations at mutually opposite angles, motion ranging from pure torsional rotation to pure bending can be obtained, depending on the comparative level and polarity of the voltages applied to each of the two electrode sets. If such elements are used as the spiral support arms of a central platform, a large displacement of the stage can be achieved. Due to the oblique orientation of the IDE's, the piezoelectric transduction induces torsional deformation in the spirals, and this torsion is converted by the spiral arms to a parallel out-of-plane platform motion. 1.

Systems and methods for micro-cantilever actuation by base excitation

Номер: US20180201497A1
Автор: Carlo Menon, Mojtaba KOMEILI
Принадлежит: Intrepid Visions Inc

A system and methods for base excitation of moderately high vibration of micro-cantilevers are disclosed. A micro-cantilever may be coupled to one or more actuators adjacent its base. The actuators may comprise bulk materials, bridges, or formed wires that expand and contract by application of electric currents, due to, for example, the effect of electro-thermal heating or piezoelectric effects. Single actuators or an array of actuators may be placed around the micro-cantilever to oscillate it and apply actuation pulses. The system and methods, and adjustments of the geometrical parameters, may be performed to yield a nominal natural frequency in the system. The excitation of actuators with signals corresponding to the natural frequency may induce resonance in the system and may result in high amplitude vibrations and displacement of the cantilever tip of the micro-cantilever. Various architectures of the actuators may be implemented to stimulate different frequencies of the beam and induce displacement in different direction and amplitudes.
