Abstract

O pedido se refere a um dispositivo (100) para amostrar não invasivamente fluido intersticial que compreende um ou mais analitos da derme (101a) para a superfície da pele (101b) com o uso do efeito magneto-hidrodinâmico. O dispositivo compreende um primeiro eletrodo (102a) e um segundo eletrodo (102b) adaptados para serem posicionados adjacentes à superfície da pele, sendo o primeiro eletrodo separado do segundo eletrodo por uma distância (103), uma fonte de alimentação (104) adaptada para induzir uma corrente elétrica através do primeiro eletrodo, do fluido intersticial e do segundo eletrodo, e também um ímã (105) adaptado para produzir um campo magnético para o fluido intersticial. A direção do campo magnético e a direção da corrente elétrica produzida pelo ímã e a fonte de alimentação, respectivamente, é de modo que a força de Lorenz dirija o fluido da derme em direção à superfície da pele.
