Abstract
Patente de Invenção: COMUTADOR MICROMECâNICO DE ACELERAçãO E COMUTADOR DE ACELERAçãO MONOLìTICO BIAXIAL. é descrito um comutador micromecânico de aceleração de silício ou materiais similares, compreendendo um elemento de eletrodo resiliente, uma massa de prova, um estojo ou alojamento e um elemento de mola conectando o elemento de eletrodo e a massa de prova ao estojo. O elemento de eletrodo é conectado mecanicamente adjacente à massa de prova. A massa de prova possui seu centro de gravidade localizado a uma dada distância do eixo geométrico através do elemento de mola, de modo que quando a massa de prova esteja pivotando em torno do eixo geométrico do elemento de mola em resposta a uma aceleração externamente aplicada, com um componente em uma direção paralela ao primeiro eixo goemétrico o elemento de eletrodo também pivota em torno deste eixo geométrico, o ângulo de pivoteamento sendo essencialmente proporcional à magnitude deste componente da aceleração. O elemento de eletrodo resiliente possui uma massa consideravelmente menor que a massa de prova e está provido com pelo menos um ponto de contato elétrico propiciando contato elétrico e cooperando com áreas de contato correspondentes no estojo de comutador em um dado ângulo de pivoteamento do elemento de eletrodo.
