摘要：

This manuscript presents a high sensitivity pressure transducer, developed at the Biometrology Laboratory of PUC-Rio for biomedical applications and examined in this article for the registration of arterial pulse waves. Such transducer is based on the Giant Magnetoimpedance (GMI) phenomenon and is an evolution of an unit previously developed at the same Laboratory. Knowing the main characteristics of the the GMI strips used as sensors, the configuration which should yield the highest possible sensitivity has been implemented and tested. The upgrade introduced to the original project has increased its sensitivity and enabled us to record not just the carotid arterial pulse wave (as the previous transducer configuration did), but also the radial and brachial arterial pulse.
