Multi-Objective Pareto Optimization of Tensile Membrane Architecture for Energy Harvesting

Abstract

With the global concern about rising greenhouse-gas emissions due to fossil-fuel-based power generation, electricity production using eco-friendly energy sources is becoming increasingly important. Conversion of vibration into electricity is characterized mainly by electrostatic, electromagnetic, or piezoelectric transduction mechanisms, which can be used to generate electricity through a variety of methods. The tensile membrane architecture (TMA)-the means of electricity production investigated in this study-is an architectural structure that is classified into the same category of vibration sources as buildings and bridges, but has not been utilized previously for vibration-generated electricity. The objective of this study is to determine which TMA geometry yields optimal electricity production and stability in a specific region. The developed optimization technique can help future researchers to select the TMA type and material for specific areas and evaluate the suitability of different areas for energy harvesting via the TMA.
