Abstract
Se presenta una barra flectora; la barra flectora incluye al menos dos pares de elementos piezoeléctricos acomodados en un elemento inerte para ajustar la frecuencia de respuesta de la barra flectora; en algunas modalidades, los elementos piezoeléctricos pueden ser apilados en el elemento inerte; en algunas modalidades, los elementos piezoeléctricos están simétricamente acomodados con respecto a la barra flectora de manera que se forma un espacio entre los elementos piezoeléctricos acomodados en el elemento inerte.
