In recent years, cardiovascular diseases are on the rise, and they entail enormous health
burdens on global economies. Cardiac vibrations yield a wide and rich spectrum of essential …

Introduction: Micro-electro-mechanical systems technology, now embedded into
smartphones, potentially allows measuring heart mechanical activity by positioning the …

Heart rate monitoring helps in assessing the functionality and condition of the cardiovascular
system. We present a new real-time applicable approach for estimating beat-to-beat time …

Objective: Systolic time intervals, such as the pre-ejection period (PEP), are important
parameters for assessing cardiac contractility that can be measured non-invasively using …

Objective: Tracking changes in hemodynamic congestion and the consequent proactive
readjustment of treatment has shown efficacy in reducing hospitalizations for patients with …

Energy harvesting is a promising solution to the limited battery lifetimes of body sensor
nodes. Self-powered sensor systems capable of quasi-perpetual operation enable the …

Malicious Hardware Trojans (HTs) that are inserted during chip manufacturing can corrupt
data which if undetected may cause serious harm in medical devices. This paper presents a …

Heart rate variability analysis is a recognized non-invasive tool that is used to assess
autonomic nervous system regulation in various clinical settings and medical conditions. A …

Corruption of data in embedded and medical devices can cause serious harm if not quickly
detected. In this paper, we emphasize the part of the attack surface which entails inserting …

Over the past century, extensive research has been conducted on interpretation of vibration
signals created by the heart and their potential use in noninvasive cardiology. Today, new …
