Abstract

This paper describes the development of a novel liquid flow sensor based on the combined use of GMR magnetic sensors and micro-fabricated ferromagnetic sensing elements. A motivating application behind this effort is the development of a “smart” ventriculo-peritoneal (VP) shunt, capable of measuring the amount cerebral-spinal fluid drained from the ventricles of a person suffering from hydrocephalous. Unlike classical liquid flow sensors based on piezo-resistive flaps, the device presented here utilizes electroplated micro-fabricated ferromagnetic flaps (Ni), while the detector is an ultra-sensitive non-contact GMR sensor, separated from the working fluid by the lumen of the shunt.
