The broken bearings and great noise and vibration often occurs with the small sugarcane harvester transfer case when it starts up working. To analyze the startup status of the transfer case conveniently and quickly, the finite element transient structure analysis is carried out. with virtual prototype technology to simulate the transfer case's startup dynamic process and measure the instantaneo...

The fabrication and characterization of a thermoelectric energy harvester using the complementary metal oxide semiconductor (CMOS)-microelectromechanical system (MEMS) technology were presented. The thermoelectric energy harvester is composed of eight circular energy harvesting cells, and each cell consists of 25 thermocouples in series. The thermocouples are made of p-type and n-type polysilic...

BACKGROUND Much research in the field of energy harvesting has sought to develop devices capable of generating electricity during daily activities with minimum user effort. No previous study has considered the metabolic cost of carrying the harvester when determining the energetic effects it has on the user. When considering device carrying costs, no energy harvester to date has demonstrated th...

The sugarcane plantations in China occupy large areas of undulated terrain. During the operation a harvester, operator’s vision is severely obstructed, and height cutter needs to be adjusted frequently, resulting low harvesting efficiency difficulty ensuring quality. However, current diversified non-contact methods are unable distinguish or penetrate interference well provide feedback regarding...

A two-stage power conditioning circuit consisting of an AC DC converter followed by a DC DC converter is proposed for a vibration-based energy harvesting system. The power conditioning circuit intends to maximize the amount of power extracted from a piezoelectric energy harvester by matching the source impedance with the circuit by adaptively adjusting the duty cycle. An equivalent electrical c...

This paper presents a new energy-harvesting system with two identical piezoelectric energy harvesters in a tandem configuration. Each harvester consists of a piezoelectric beam and a circular cylinder. Experiments are performed to investigate the energy-harvesting performances of this system in water. It can be found that their energy-harvesting performances are all different from that of the s...

In this paper, a 9 degree of freedom seaweed harvester dynamical model is presented. The model presented describes the coupled dynamics of a vessel and a harvesting device, lifted by a winch, subject to sea waves disturbances. In order to find an appropriate harvesting path, which minimizes the harvester motions, the model response is simulated for different encounter angles. This 9 DOF seaweed...
