摘要： A vortex-induced vibration wind energy harvesting device, including an array consisting of a plurality of oscillators and a plurality of piezoelectric microelectromechanical systems (MEMSs), is provided. An oscillator is mounted on each of the piezoelectric MEMSs. When any one of the oscillators is oscillated by and resonant with vortex shedding due to an incoming airflow, its vortices in the wake will enhance the oscillation of the downstream oscillators, so that overall oscillation of the oscillators in the array is strengthened. The piezoelectric MEMSs are deformed by the vibration of these oscillators to generate voltage and current to output. In the present invention, the oscillators are arranged closely. When the airflow passes the array, even weak airflow can generate periodic force and cause significant oscillation due to resonance. The MEMS can convert mechanical energy into electrical energy and output it in order to achieve the purpose of wind energy harvesting.

摘要： A method of fabricating a thin film with a varying thickness includes the steps of providing a shadow mask with an opening, providing a carrier plate, arranging a substrate on the carrier plate, and coating the substrate through the opening whilst rotating the carrier plate relative to the shadow mask. A plurality of zones of the substrates is swept and exposed from arcuate portions of the opening per each turn by a plurality of predetermined exposure times, respectively. The varying thickness of the thin film corresponds to variation of the predetermined exposure times.

摘要： A quasi-single-crystal film and its manufacturing method thereof are provided, in which a metal film having a preferred orientation of on its surface is subjected to a mechanical stretching force, such that the crystal grains thereof are able to form in a much more orderly arrangement, and a quasi-single-crystal film having preferred orientations on three axes can be obtained. The proposed quasi-single-crystal film has preferred orientations of and on its stretching direction and a direction that is perpendicular to the stretching direction, respectively, and retains a preferred orientation of on its surface. By employing the present invention, it is advantageous of manufacturing large-area quasi single crystal films having high anisotropy as well as growing two dimensional materials or developing of other anisotropic feature structures.

摘要： A signal processing method is provided. First, at least one transmitted signal is output to at least one target, and the target reflects at least one reflected signal to receiving antennas, which then generate receiving signals upon receipt of the reflected signal. Next, the transmitted signal and each receiving signal are processed to generate processing signals. The processing signals are arranged in a form of matrix, to generate a channel coefficient matrix having M×N channel coefficient matrix blocks. Next, the channel coefficient matrix is divided into Ndivide×Mdivide secondary channel coefficient matrices, which are then substituted into a snapshot vector matrix equation to generate a snapshot vector matrix for calculating an angle of the target. The signal processing method can establish an optimal secondary channel coefficient matrix arrangement by using a special signal preprocessing manner, to improve the resolution and accuracy of the estimated angle parameter of the target.
