Simulation-aided workflow toward dynamic fluid phantoms for impedance plethysmography

Abstract

Impedance plethysmography (IPG) is recently gaining traction as a non-invasive sensing technique suitable for wearable devices, such as smartwatches. In this context, dynamic fluid phantoms can provide well-defined test scenarios to enable algorithm design and training. We outline the initial steps of our phantom design process, which relies on a combination of simulation studies and experiments. We conducted measurements in saline solutions and implemented a corresponding simulation of a time-varying pulse wave. Our overarching goal is the integration of an IPG component into a multi-modal dynamic fluid phantom.
