SENSOR SYSTEM FOR MEASURING FLOW VELOCITY AND PRESSURE

A sensor system comprises a piezoelectric sensor for measuring flow and first and second piezoresistive pressure sensors for measuring pressure. The sensors are at a distal portion of an elongate support such as a catheter or guidewire, which comprises first, second and third conductors, shared betw...

description	A sensor system comprises a piezoelectric sensor for measuring flow and first and second piezoresistive pressure sensors for measuring pressure. The sensors are at a distal portion of an elongate support such as a catheter or guidewire, which comprises first, second and third conductors, shared between the two sensor types. A time-interleaved readout of the sensor signals is used. Un système de détection comprend un capteur piézoélectrique destiné à mesurer l'écoulement et des premier et second capteurs de pression piézorésistifs pour mesurer la pression. Les capteurs se situent au niveau d'une partie distale d'un support allongé tel qu'un cathéter ou un fil-guide, qui comprend des premier, deuxième et troisième conducteurs, partagés entre les deux types de capteurs. Un affichage à entrelacement temporel des signaux de détection est utilisé.
