…will help researchers all over the world… design optimised energy harvesting units for custom applications…
Excerpts from Electronic Product Design & Test:
A triboelectric nanogenerators (TENG) is an energy harvesting device that uses the contact between two or more (hybrid, organic or inorganic) materials to produce an electric current.
Researchers from the Advanced Technology Institute (ATI) of the University of Surrey (UK) have provided a step-by-step guide on how to construct the most efficient energy harvesters. The study introduces a ‘TENG power transfer equation’ and ‘TENG impedance plots’: tools which can help improve the design-for-power output of TENGs.
As Professor Ravi Silva, director of the ATI explains: “A world where energy is free and renewable is a cause that we are extremely passionate about here at the ATI (and the University of Surrey) – TENGs could play a major role in making this dream a reality… TENGs are ideal for powering wearables, internet of things devices and self-powered electronic applications. This research puts the ATI in a world-leading position for designing optimised energy harvesters.”
Excerpts from Popular Science Nexus Media News:
…some estimates have the use of TENGs costing less than 3 cents per kWh, “although the actual cost for these devices is still to be evaluated, especially when it comes to large scale manufacturing,” he said. “However, TENGs can be made with common low-cost materials, with easy methods, therefore they can be cheap to make. Hence, scaling up TENGs is definitely a possibility in the near future.” – Ishara Dharmasena, a doctoral student at ATI, and lead scientist on the project
