摘要:
A micro assembly having a substrate and an operating plane coupled to the substrate. The operating plane is movable from an in-plane position to an out-of-plane position. One or more electric connections provide electric power from the substrate to the operating plane in the out-of-plane position. A tool is coupled to the operating plane. The tool is operable to receive electric power from the operating plane to perform work.

The present disclosure provides a displacement amplification structure and a method for controlling displacement. In one aspect, the displacement amplification structure of the present disclosure includes a first beam and a second beam substantially parallel to the first beam, an end of the first beam coupled to a fixture site, an end of the second beam coupled to a motion actuator, and a motion shutter coupled to an opposing end of the first and second beams. In response to a displacement of the motion actuator along an axis direction of the second beam, the motion shutter displaces a distance along a transversal direction substantially perpendicular to the axis direction.

Actuators (artificial muscles) comprising twist-spun nanofiber yarn or twist-inserted polymer fibers generate torsional and/or tensile actuation when powered electrically, photonically, chemically, thermally, by absorption, or by other means. These artificial muscles utilize non-coiled or coiled yarns and can be either neat or comprising a guest. Devices comprising these artificial muscles are also described.
摘要:
The invention relates to a device for converting heat energy into mechanical energy comprising a first (4) and a second (6) bistable area passing from a first stable state to a second stable state by means of a thermal effect or mechanical action, said areas (4, 6) being mechanically coupled such that the passage from one state to the other of one area (4, 6) by means of a thermal effect causes the other area (6,4) to pass from one state to the other, each area (4, 6) having a blistering temperature and an unblistering temperature, the blistering temperature being higher than the unblistering temperature. Said device is intended to be placed in contact with an environment (SC) having at least one given temperature, such that the temperature of the environment (SC) is lower than the blistering temperature of the first area (4) and is higher than the blistering temperature (Tc6) of the second area (6).
摘要:
Method for harvesting energy using an EAP based deformable body. The EAP based deformable body is an elastically deformable body including an arrangement of stretchable synthetic material and electrodes being arranged as a variable capacitor with a capacitance that varies as the deformable body stretches and relaxes. The method includes: looping through an energy harvesting cycle with a) stretching the deformable body from a minimal relaxed size L1 to a maximal stretched size L2; b) at the maximal stretched size electrically charging of the variable capacitor to create an electric field over the capacitor with an upper electric field level value; and subsequently c) a relaxation step from maximal stretched size to the minimal relaxed size; d) at the minimal relaxed size of the deformable body, electrically discharging the capacitor to a minimal charge level and a minimal electric field level value.
