Abstract
APARELHO PARA MEDIR IMPEDáNCIA ELéTRICA DE AMOSTRAS DE TECIDO. A presente invençâo fornece um aparelho para medir a impedância elétrica de uma amostra de tecido compreendendo uma sonda e um revestimento compreendendo um corpo tubular alongado com uma extremidade fechada e uma extremidade aberta e definindo uma cavidade interna, O revestimento é composto de um material que quando em contato com uma amostra de tecido é capaz de fornecer um percurso condutivo através do revestimento entre os eletrodos e a amostra de tecido. A resistividade do material que forma o revestimento quando em contato com a amostra de tecido é maior do que a resistividade da amostra de tecido. A sonda é recebida dentro da cavidade interna do revestimento, O revestimento é impermeável a baqtérias e vírus.
