Abstract

tornar variável o alcance de detecção e a precisão de detecção de um dispositivo de sensor que usa a deformação de um elastômero viscoelástico. um dispositivo de sensor (1) que tem um elastômero viscoelástico magnético (2) que contém partículas magnéticas condutivas (15) dispersas no mesmo, um módulo elástico que varia de acordo com a intensidade de um campo magnético aplicado e um valor de resistência elétrica em uma direção prescrita que muda de acordo com a deformação; meios de aplicação de campo magnético (5,6) que aplicam um campo magnético ao elastômero viscoelástico magnético e têm capacidade de alterar a intensidade do campo magnético aplicado; um meio de detecção de resistência (35) para detectar a resistência elétrica do elastômero viscoelástico magnético; e um meio de cálculo (10) para calcular pelo menos o estado de deformação do elastômero viscoelástico magnético ou a carga aplicada ao elastômero viscoelástico magnético com base no valor de detecção do meio de detecção de resistência e a intensidade do campo magnético aplicada pelos meios de aplicação de campo magnético.
