Microstructured hybrid actuator assemblies in which microactuators carrying designed surface properties to be revealed upon actuation are embedded in a layer of responsive materials. The microactuators in a microactuator array reversibly change their configuration in response to a change in the environment without requiring an external power source to switch their optical properties.

Semiconductor nano-devices, such as nano-probe and nano-knife devices, which are constructed using graphene films that are suspended between open cavities of a semiconductor structure. The suspended graphene films serve as electro-mechanical membranes that can be made very thin, from one or few atoms in thickness, to greatly improve the sensitivity and reliability of semiconductor nano-probe and nano-knife devices.

A method of fabricating a MEMS composite transducer includes providing a substrate having a first surface and a second surface opposite the first surface. A transducing material is deposited over the first surface of the substrate. The transducing material is patterned by retaining transducing material in a first region and removing transducing material in a second region. A polymer layer is deposited over the first region and the second region. The polymer layer is patterned by retaining polymer in a third region and removing polymer in a fourth region. A first portion of the third region is coincident with a portion of the first region and a second portion of the third region is coincident with a portion of the second region. A cavity is etched from the second surface to the first surface of the substrate. An outer boundary of the cavity at the first surface of the substrate intersects the first region where transducing material is retained, so that a first portion of the transducing material is anchored to the first surface of the substrate and a second portion of the transducing material extends over at least a portion of the cavity.

Processes for making a profile-transferring substrate surface and membranes having curved features are disclosed. A profile-transferring substrate surface having a curved feature is created by isotropic plasma etching through a shadow mask. The shadow mask has a through hole which has a lower portion adjacent to the bottom surface of the shadow mask and an upper portion that is above and narrower than the lower portion. The isotropic plasma etching through the shadow mask can create a curved dent in a planar substrate in a central portion of an area enclosed by the bottom opening. After the shadow mask is removed. A uniform layer of material deposited over the exposed surface of the substrate will include a curved feature at the location of the curved dent in the substrate surface.

The device comprises a first actuating bump made from electrically conducting material with a first contact surface. A second actuating bump made from electrically conducting material is facing the first actuating bump. An electrostatic actuating circuit moves the actuating bumps with respect to one another between a first position and another position. The actuating circuit comprises a device for applying a higher potential on the second actuating bump than on the first actuating bump. A film of electrically insulating material performs electric insulation between the first and second bumps. The electrically insulating material film comprises an interface with a positive ion source and is permeable to said positive ions.

A motion conversion system is described. The motion conversion system comprises a first torsional member operative for rotating in a first direction. A second torsional member is offset a distance from the first torsional member, wherein the second torsional member is operative for rotating in a direction opposite from the first direction. And, a lateral member has a lower surface connected to the first and second torsional members. Wherein, translational movement of the lateral member results from rotational movement of the first and second torsional members.

A package to receive a memory device including an electromagnetic motor comprises a body having a top surface and a bottom surface. Conductive leads extend through the body so that the conductive leads are at least partially exposed within the package. A base is connectable with the bottom surface of the body, and a lid is connectable with the top surface of the body. The base and the lid have substantially matched thermal expansion characteristics and provide magnetic flux return paths for the electromagnetic motor.
