Abstract

"SISTEMA PARA GERAR ENERGIA ELéTRICA EM UM VEìCULO, E, PNEU PARA UM VEìCULO". Um sistema para gerar energia elétrica em um pneu de veículo (1) compreendendo pelo menos um elemento piezoelétrico (9; 109) associado ao pneu (1) que geras energia elétrica sempre que é deformado, e este elemento piezoelétrico (9; 109) ser alongado, estender-se ao longo de pelo menos uma porção do pneu (1) e ser conectado eletricamente a um circuito elétrico que é aplicado ao mencionado pneu (1) e não em comunicação elétrica com o veículo. O elemento piezoelétrico (9; 109) compreende, de preferência, um cabo coaxial (10) estendendo-se ao longo de um caminho reto ou ondulado da circunferência do pneu."SYSTEM FOR GENERATING ELECTRIC POWER IN A VEHICLE, AND, TIRE FOR A VEHICLE". A system for generating electrical energy in a vehicle tire (1) comprising at least one piezoelectric element (9; 109) associated with the tire (1) that generates electrical energy whenever it is deformed, and this piezoelectric element (9; 109) is elongate, extend over at least a portion of the tire (1) and be electrically connected to an electrical circuit that is applied to said tire (1) and not in electrical communication with the vehicle. The piezoelectric element (9; 109) preferably comprises a coaxial cable (10) extending along a straight or wavy path of the circumference of the tire.
