  • Self-powered delineator including lighting-emitter
    Patent number: 11505905
    Abstract: A self-powered delineator includes a wind-powered rotatable module; a first piezoelectric energy generator module for generating electrical energy; a second piezoelectric energy generator module for generating electrical energy; and a light-emitter. The wind-powered rotatable module includes one or more first magnets spacedly arranged around a rotation shaft. The first piezoelectric energy generator module includes one or more first piezoelectric elements, and one or more second magnets disposed on the at least one first piezoelectric element. The second piezoelectric energy generator module includes at least one elastic base extending radially from a fixed shaft in a cantilever manner; and at least one second piezoelectric element on the at least one elastic base.
