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, or engines of cars and construction equipment.
Some tech companies use piezoelectric ceramic materials to harvest electricity from waste vibrations, 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) for energy harvesting.
Energy can be harvested from waste vibrations to power lights and recharge batteries.
