Engineering#13 in February 2026 EditionWearable ultrasound patches for continuous non-invasive cardiac output and ventricular volume monitoring
Beatrice Moretti, Carlos Gomez, Sunita Roy et al.
OPENSTEM EDITORIAL SUMMARY
What the research examines
A stretchable, conformal 128-element piezoelectric ultrasound phased array patch adheres to the chest wall, continuously imaging the left ventricle in motion and computing real-time stroke volume, cardiac output, and ejection fraction during vigorous exercise.
Why it may matter
Transforms cardiovascular clinical monitoring from episodic hospital echocardiograms into 24/7 outpatient ambulatory care.
What to examine carefully
Rib acoustic shadowing and heavy patient respiration introduce periodic acoustic beam blockages.
Editorial scope: This is a concise, independently written introduction based on the publisher information, not a full systematic review or independent replication. It must not replace reading the original methods, limitations and conclusions.
STUDENT RESEARCH LENS · ORIGINAL OPENSTEM NOTES
Try a small, reproducible follow-up
Extract ventricular end-diastolic and end-systolic dimensions from B-mode ultrasound frames to compute stroke volume via Teichholz equations.
Questions to investigate
- How did stretchable liquid metal interconnects maintain electrical continuity under 40% mechanical skin strain?
- What statistical agreement (Bland-Altman analysis) was proven against invasive pulmonary artery catheter standards?
These are independently proposed educational investigations, not activities that the original research authors claim to have completed.
