Abstract

trata-se de um sistema e método para monitorar um indivíduo. o sistema inclui um dispositivo de captação que inclui pelo menos uma fonte magnética para gerar um campo magnético e uma matriz de sensores magnéticos dispostos dentro do campo magnético. a matriz de sensores obtém uma pluralidade de medições de campo magnético em uma pluralidade de locais ao longo de um vaso que transporta um fluido que inclui uma ou mais partículas magnéticas. ademais, o sistema inclui um subsistema de processamento acoplado comunicativamente ao dispositivo de captação, em que o subsistema de processamento determina variações nas medições provocadas por magnetização-relaxação das partículas magnéticas com base em um modelo acoplado que define o comportamento do fluido no campo magnético variável com base em princípios de magnetização-relaxação, movimento em massa das partículas magnéticas em direção a um gradiente determinado do campo magnético, magnetostática e conservação de momento. o subsistema de processamento estima valores de um ou mais parâmetros desejados com base nas variações determinadas.
