Energy Harvesting from Structural Movements Enhanced by Origami

In this project the techniques of origami and kirigami will be used to amplify the deformation of structural elements to optimise energy harvesting using piezoelectric materials.

Project Description

Despite their solid appearance civil engineering structures are constantly moving. This can be the result of wind, thermal changes, occupancy, traffic, or other actions. These movements introduce energy into the structural system in the form of structural deformations (strain energy) and vibrations (kinetic energy). This energy can be harvested using piezoelectric materials and used to power electrical systems. Piezoelectricity is the property of a material which creates an electric potential when subjected to mechanical strain; quartz is a naturally occurring example of a piezoelectric material. The use of piezoelectric materials for energy harvesting has so far been limited to low-power applications. To improve power output this project takes inspiration from origami and kirigami, the art of paper folding and cutting respectively, to amplify structural movement and increase the power output of piezoelectric energy harvesting. This will reduce the need for external energy generation and its associated environmental impact.
