Power and Energy Harvesting Efficiency Under Different Environmental Sources Using Piezoelectric Mechanism for Industrial Applications

Engineering has evolved from perceptions of the ways natural and constructed systems respond and from the improvement of empirical formulas that give bases to design. Centuries before it was known that engineering consists of just two fields, military and civil, civil engineering remains an umbrella term including numerous related specialties. As a result of increasing the cost of non-renewable energy resources, the world trends to find other renewable and sustainable resources for supplying power to electronic devices, generators, and much more applications. It's also worth mentioning that generating electricity in traditional ways is considered a complex method. Energy harvesting is defined as scavenging energy from the environment or natural resources such as wind, rain, waves, human activities, and earthquakes for (Structural Health Monitoring) SHM purposes, Piezoelectric mechanism is chosen in this paper for energy harvesting because of its advantages compared to other mechanisms such as its smaller size, fewer moving parts, simpler design, and its higher efficiency. This paper includes the energy efficiency investigation for different energy sources of vibration such as wind, rainfall, and earthquake using MATLAB Simulink environment. The wind is considered the most efficient source due to the high power values that can be obtained, and its continuity under all circumstances.
