welding rod-What is Piezoelectricity?
The word piezoelectricity comes from the Greek word piezein, which means squeeze or press and electron, which means “amber” and is an ancient source of electric charge.The French physicists Jacques and Pierre Curie discovered in 1880 that electric charges could accumulate in certain solid materials in response to an applied mechanical stress.Piezoelectric materials allow conversion of energy from the mechanical domain to the electrical domain and vice versa. They can be used to create various sensors or actuators: applied periodic electrical signal can result in the generation of ultrasonic waves for imaging purposes.
