Avaliação do desempenho de um sensor biotelemétrico passivo para monitoração da pressão arterial - testes estáticos

Abstract

The purpose of this paper is to describe a passive biotelemetric sensor for arterial blood pressure monitoring. The sensor has been developed using a glass tube, sized 5.5 x 11 mm, closed at one side with the other covered by a thin policys- isoprene membrane and, a ferrite core attached to it. The displacement of the ferrite core modulates the resonance frequency of LC circuit located at the tube bore, which can be evaluated remotely. The static results of the sensor are presented and discussed in details. © Springer-Verlag Berlin Heidelberg 2007.
