Shape Design Optimization of Unimorph Piezoelectric Cantilever Energy Harvester

The most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy. Using piezoelectric cantilevers is the most common method for vibration energy harvesting. Changing the shape of the cantilevers can lead to changing the generated output voltage and power. In this work vibration energy harvesting via piezoelectri...

Design, integration, and field evaluation of a robotic apple harvester

Design, construction and testing of an apricot tractor-trailed harvester

The purpose of this research is to facilitate the mechanical harvesting of apricots (Prunus armeniaca L.) for industry. A tractor-trailed harvester was built to catch the fruits detached from apricot (cv. Búlida) trees by vibratory systems. This machine is a low profile catcher that can move under the trees in high-density canopies where umbrella-type harvesters cannot. The trailer is able to w...

Design and Development of Eggplant Harvester for Gantry System

This paper describes the design and development of harvesting system for the gantry system to harvest eggplants. For this purpose, the harvesting robot was successfully designed and fabricated for the gantry system to harvest eggplants. The operation of the harvester was controlled by Programmable Logic Controller (PLC). Basically, the limit switches, DC motor, and relay are connected to the PL...

Design optimization and experimental analysis of Piezoelectric Energy harvester

This paper describes an approach to harvest electrical energy from a mechanically excited piezoelectric element. The structure of piezoelectric energy harvester is optimized for maximum power with minimum dimensions through Genetic Algorithm approach to enhance the conversion of mechanical energy into electrical energy using direct piezoelectric effect.
