Lightweight Ceramic Material Harvests Electricity From Vibrations
A new ceramic material offers a lightweight, thermally stable, and fatigue-resistant option for harvesting waste energy.
There is a significant amount of potential energy in vibrations produced by footsteps, exercise machines, and engines of cars and construction equipment.
Some tech companies have begun to harvest electricity from waste vibrations using piezoelectric ceramic materials, which emit electrical charges when manipulated.
A team led by materials scientists at Penn State has improved the structure and chemistry of a piezoelectric material made of potassium sodium niobate (KNN) to expand energy harvesting efforts.
