Energy Conversion of Parametric Pendulum and its Application for Vibration Energy

Vibration Energy Harvesting and Its Application for Nano- and Microrobotics

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...

Non-Parametric Energy Use Efficiency, Energy Ratio and Specific Energy for Irrigated Wheat Crop Production

In this paper, non parametric Data Envelopment Analysis (DEA) was subjected to the energy data of wheat producers in Punjab state, India, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. The main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...

Electromechanical pendulum for vibration control and energy harvesting

This paper presents the design of an experimental electromechanical device for vibration control and energy harvesting. Traditionally, when the broadband resonant response due to a selected mode of a lightly damped structure needs to be controlled a vibration absorber is used. The resonance frequency of the absorber can be chosen to minimise the response of the structure under control. Optimisi...

Electrostatic Conversion for Vibration Energy Harvesting

Electrostatic vibration-to-electric energy conversion

Ultra-Low-Power electronics can perform useful functions with power levels as low as 170 nW. This makes them amenable to powering from ambient sources such as vibration. In this case, they can become autonomous. Motivated by this application, this thesis provides the necessary tools to analyze, design and fabricate MEMS devices capable of electrostatic vibration-to-electric energy conversion at...
