A Highly Integrated Computing Platform for Continuous, Non-Invasive BP Estimation

Abstract

Bio-Signal computing involves signal acquisition, conditioning and processing. Inherently, signal acquisition and conditioning is done through analog discrete front end circuitry. Signal processing in the analog domain involves higher component counts, inaccuracies, and limitations. Due to the recent developments in VLSI technology, highly integrated Analog Front Ends (AFEs) are emerging, capable of processing bio-signals under program control. This ushers a new design paradigm for the embedded system designers. In this paper, we present a highly integrated AFE based embedded system-a novel, low cost remote platform, capable of multimodal bio-signal computing including continuous, and non-invasive blood pressure estimation.
