With the development of low power electronics and energy harvesting technology, selfpowered systems have become a research hotspot over the last decade. The main advantage of self-powered systems is that they require minimum maintenance which makes them to be deployed in large scale or previously inaccessible locations. Therefore, the target of energy harvesting is to power autonomous ‘fit and ...

prior to the design and construction of any fruit harvesting machine it is essential to know the physical and mechanical properties of the trees and of its fruits. an example could be cited as the force needed to overcome. the strength with which the fruit is attached to the stem, in trunk shaker harvesting. in this research the acting forces on the fruit during harvest, including tensile stren...

rapeseed cultivation in iran is growing rapidly while this product has been facing specific problems. every year a significant portion of edible oil is imported to the country from other countries. despite this deficit, a great amount of canola is being lost every year. therefore, in compliance with technical points, adding a suitable platform to the exisiting machineries may reduce the losses....

In this chapter, the concept of vibration energy harvesting and its potential utilization as a power source for micro/nanorobots is introduced and discussed. While batteries are commonly used as power sources for electronic devices, the limited lifetime and relatively large dimensional structure of batteries constrain its applications in micro/nanodevices. On the other hand, while capacitors ha...

The plants and its produce characteristics are the basis to design a crop specific harvester. objective of this study was determine physical, morphological mechanical properties chilli fruits, that can be used in harvester machine. observations data were collected by taking measurements at harvesting stage three cultivars. fruit bearing behavior solitary with position erect Demon F1 pendent Ara...

Passive energy harvesting from mechanical vibration has wide application in wearable and embedded sensors to complement or replace batteries. Energy harvesting efficiency can be increased by eliminating AC/DC conversion. A test chip demonstrating self-timing, power-on-reset circuitry, and memory for energy harvesting AC voltages has been designed in 180 nm CMOS and tested. Circuit operation is ...

Over the last decade electrical batteries have emerged as a critical bottleneck for portable electronics development. High-power mechanical energy harvesting can potentially provide a valuable alternative to the use of batteries, but, until now, a suitable mechanical-to-electrical energy conversion technology did not exist. Here we describe a novel mechanical-to-electrical energy conversion met...

IO N The harvesting of energy from the environment dates back to the age of the windmill and the waterwheel. Their modern counterparts are hydro-power plants, wind farms, solar farms, and more recently, novel piezoelectric devices [ 1 ] for power generation from mechanical vibration. [ 2 ] Fully utilizing power sources such as light, [ 3–5 ] thermal, and mechanical energy is of great importance...
