Abstract

aparelho e método de medição de potencial de couro cabeludo. descreve-se um aparelho para medição de potencial de couro cabeludo, o qual compreende uma pluralidade de sensores e um pré-amplificador acoplado a esses sensores. os sensores são adaptados para medir uma medição de potencial de couro cabeludo bruto através de um cabelo e uma interface de ar e pode ser considerado como uma diferença, referência ou medição comum. a interface apresenta uma impedância de fonte variável e elevada acoplada ao couro cabeludo. o pré-amplificador é adaptado para ter uma impedância de entrada significantemente mais elevada do que aquela apresentada pela interface de fonte, e receber a medição de potencial de couro cabeludo bruto para produzir uma produção de potencia de couro cabeludo pré-amplificada.
