Vital Signs Acquisition ASIC platform (BELICIM)

The low-power implantable ASIC includes bio-impedance and ECG measurement read-outs for proactive management of heart failure.

Application

This ASIC is part of an innovative digital stethoscope implanted in the digestive tract of a patient by endoscopy.  

The goal is to provide a tele-monitoring solution to track physical and cardio-respiratory vital signs of a patient and prevent acute cardiac decompensations, thus reducing re-hospitalizations for relapsing heart failure.
