Abstract

manga de sensor monitoramento de saúde de um artigo. uma manga de sensor (10) para uso na detecção de uma falha em uma artigo (18) (por exemplo, uma mangueira hidráulica), a manga de sensor incluindo uma camada isolante (12), que se separa duas camadas de eletrodo (14, 16). com tal, as camadas de eletrodo deformam para contatar uma à outra, o que muda a impedância como medida através das camadas de eletrodo. a manga de sensor é projetada para mudar a impedância elétrica ( resistência) devido à pressão de fluido iniciado um furo através do sensor propriamente dito. a manga de sensor detectará o vazamento de fluido quando o furo penetrar o sensor e colocará os dois eletrodos elásticos em contato um com o outro e/ou o fluido, que quando o fluido é fluido condutor, cria um percuso de sinal entre a primeira camada de eletrodo e a segunda camada de eletrodo, que também muda a impedância como medida através das camadas de eletrodo.
