A new ceramic material offers a lightweight, thermally stable, and fatigue-resistant option for harvesting waste energy.
Vibrations from footsteps, exercise machines, or engines produce a significant amount of potential energy.
Some tech companies use piezoelectric ceramic materials to harvest electricity from waste vibrations, powering lights and recharging batteries.
These materials emit electrical charges when stepped on or 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), expanding early efforts in energy harvesting.
