This paper presents a novel tunable multi-frequency hybrid energy harvester (HEH). It consists of piezoelectric (PEH) and an electromagnetic (EMEH), which are coupled with magnetic interaction. An electromechanical coupling model was developed numerically simulated. The effects force, mass ratio, stiffness mechanical damping ratios on the output power were investigated. A prototype fabricated characterized by experiments. measured first peak increases 16.7% 833.3% compared that EMEH PEH,...
A novel piezoelectric energy harvester equipped with two beams and cylinders was proposed in this work. The can convert the kinetic of water into electrical by means vortex-induced vibration (VIV) wake-induced (WIV). effects load resistance, velocity cylinder diameter on performance were investigated. It found that upstream VIV which enhanced harvesting capacity beam. As for downstream cylinder, both WIV could be obtained. small L/D, e.g., 2.125, 2.28, 2.5, 2.8. Additionally, stimulated...
This work presents a novel bird-shaped broadband piezoelectric energy harvester based on two-DOF crossed beam for low-frequency environmental vibrations. The features cantilever mounted double-hinged beam, whose rotating motions effectively diminish its natural frequencies. Numerical simulation the finite element method is conducted to analyze modal shapes and harmonic response of proposed harvester. Prototypes are fabricated experiments carried out by testing system, results indicate good...
Flow-induced energy harvesting has attracted more and attention among researchers in both fields of the wind fluid. Piezoelectric harvesters triboelectric nanogenerators are exploited to obtain superior performance sustainability, electromagnetic conversion been continuously improved meantime. Aiming at different circumstances, have designed, manufactured, tested a variety harvesters. In this paper, we analyze state-of-the-art techniques categorize them based on working environment,...
In this work, we show that it is feasible to perform multiple tasks concurrently on point cloud with a straightforward yet effective multi-task network. Our framework, Poly-PC, tackles the inherent obstacles (e.g., different model architectures caused by task bias and conflicting gradients dataset domains, etc.) of learning cloud. Specifically, propose residual set abstraction (Res-SA) layer for efficient scaling in both width depth network, hence accommodating needs various tasks. We...
Active reducing the skin friction drag of vehicles (such as missiles, rockets, aircraft, high-speed train, submarines, etc.) during navigation process can improve respond speed effectively, save energy consumption and increase endurance time. As lots active reduction methods were proposed for different applications, a review article is urgently needed to guide researchers choose suitable their pre-research. In this review, generation mechanisms under action disturbing turbulent boundary...
This paper proposes a novel and efficient energy harvester (EH) system, for capturing simultaneously flutter vortex-induced vibration. There exists coupling effect between flexible spring (FSEH) cantilever beam (CBEH) in aerodynamic response output characteristic. Many prototypes of the were manufactured to explore wind tunnel. The experimental results demonstrate that FSEH is mainly subjected flutter-induced vibration CBEH undergoes Disturbance first takes place, limited oscillation cycle...
