Digital blood pressure meter design using PIC microcontroller

Posted on by Leave a comment

This Application Note from Microchip provides a reference design for building a non-invasive blood pressure meter using the PIC24FJ128GC010 microcontroller and MCP6N11 instrumentation amplifier.

A digital blood pressure meter measures systolic and diastolic pressures by oscillometric detection. Microchip’s digital blood pressure meter demo can measure blood pressure and pulse rate during inflation. The Measurement While Inflating (MWI) principle
reduces overall measuring time, which in turn reduces discomfort caused by the pressure in the cuff.

The OpenHardwareExG project is aimed to develop an open source hardware and software platform for electrophysiologic signal processing applications, including ECG, EEG, EMG, ENG, and EOG. The current version of the design is based on an ADS1299 analog front end for capturing electrophysiologic signals and integrates an Arduino Due compatible microcontroller along with 5kV of reinforced isolation for safety.
