摘要： An active cooling system and method for using the active cooling system are described. The active cooling system includes a cooling element having a first side and a second side. The first side of the cooling element is distal to a heat-generating structure and in communication with a fluid. The second side of the cooling element is proximal to the heat-generating structure. The cooling element is configured to direct the fluid using a vibrational motion from the first side of the cooling element to the second side such that the fluid moves in a direction that is incident on a surface of the heat-generating structure at a substantially perpendicular angle and then is deflected to move along the surface of the heat-generating structure to extract heat from the heat-generating structure.

摘要： A power generation element includes a magnetostrictive plate, a coil enclosing at least a part of the magnetostrictive plate, a magnetic field generation portion that generates a magnetic field, a yoke including a ferromagnetic body, and a non-magnetic body. The magnetostrictive plate contains a magnetostrictive material and has one fixed end. The power generation element generates power when force is applied to the magnetostrictive plate. The yoke spans from one towards another partial area of the magnetostrictive plate. The one partial area of the magnetostrictive plate, the non-magnetic body, and one end of the yoke at the one partial area of the magnetostrictive plate are disposed in this order. Another end of the yoke faces the other partial area through a gap. The one partial area is on one surface of the magnetostrictive plate and the magnetic field generation portion is provided on another surface of the magnetostrictive plate.

摘要： The disclosure belongs to the technical field of additive manufacturing, and discloses a flexible piezoelectric sensor based on 4D printing and a preparation method thereof. The sensor includes a magnetic part and a conductive part, wherein: the conductive part includes two substrates disposed opposite to each other and a spiral structure disposed between the two substrates. Both the two substrates and the spiral structure are made of conductive metal materials. The magnetic part has a flexible porous structure and is arranged between the two substrates to generate a magnetic field. When the substrate is subjected to external pressure, the spiral structure and the magnetic part are compressed simultaneously, the magnetic flux passing through the spiral structure changes, and the voltage of the two substrates changes, by measuring the voltage change of the two substrates to reflect the change of external pressure, the pressure measuring process is achieved.

摘要： A cooling system and method for using the cooling system are described. The cooling system includes an array of cooling elements and a controller. The array of cooling elements corresponds to regions of the heat-generating structure where heat is generated in response to operation of the semiconductor. The controller is configured to activate portions of the array of cooling elements based on a determination that operation of the heat-generating structure is likely to generate heat in a given region of the heat-generating structure.

摘要： A matching control method for mechanical impedance of a magnetostrictive precision transducer includes developing a three-layer neural network model corresponding to a Young's modulus of a Terfenol-D material; acquiring sample data to form a training sample set and a testing sample set; training the model using a Bayesian regularization training algorithm, and optimizing connection weights and thresholds among layers of the tested model, so as to obtain a final three-layer neural network model; based on the final model, building an inverse model of mechanical impedance of the magnetostrictive precision transducer; using a current level of impedance of a load as an input of the inverse model to obtain a bias magnetic field, and changing a level of the bias magnetic field by changing a bias current in an excitation coil of the transducer, thereby achieving adaptive matching between the mechanical impedance of the transducer and the impedance of the load.
