Abstract

MéTODO E DISPOSITIVO PARA DETERMINAR UM PARáMETRO DE TECIDO VIVO. A presente invenção refere-se a um dispositivo para medir um nível de glicose ou algum outro parâmetro de tecido vivo que afeta as propriedades dielétricas do tecido. O dispositivo compreende uma disposição de eletrodo (5) que apresenta uma pluralidade de eletrodos (5-i). O sinal de uma fonte de sinal (31) pode ser aplicado à disposição de eletrodo através de uma montagem de comutação (39). A montagem de comutação (39) é projetada para seletivamente conectar um primeiro e um segundo padrões dos eletrodos (5-i) à fonte de sinal, gerando assim um primeiro e um segundo campos elétricos com a distribuição espacial diferente no tecido. Com o uso de um método diferencial que conta com a medição da impedância da disposição de eletrodo (5) para cada campo e com a subtração adequada dos resultados medidos, os efeitos de superfície podem ser reduzidos e o foco da medição pode ser deslocado para um ponto mais profundo dentro do tecido.
