Photoplethysmography is a key sensing technology which is used in wearable devices such
as smartwatches and fitness trackers. Currently, photoplethysmography sensors are used to …

Piezoelectric arterial pulse wave dynamics are traditionally considered to be similar to those
of typical blood pressure waves. However, achieving accurate continuous blood pressure …

Portable and timely monitoring of blood pressure (BP) is critical for early prevention and
daily control of hypertension. Despite tremendous efforts, achieving a wearable and …

In this paper, a machine learning (ML) approach to estimate blood pressure (BP) using
photoplethysmography (PPG) is presented. The final aim of this paper was to develop ML …

Purpose Respiratory rate can provide auxiliary information on the physiological changes
within the human body, such as physical and emotional stress. In a clinical setup, the …

Blood pressure (BP) responds instantly to the body's conditions, such as movements,
diseases or infections, and sudden excitation. Therefore, BP monitoring is a standard clinical …

Background: Non-invasive tracking of beat-to-beat pulse transit time (PTT) via piezoelectric/
piezocapacitive sensors (PES/PCS) may expand perioperative hemodynamic monitoring …

In this paper the authors propose the development of a driver monitoring system (DMS) that
can be proven useful to improve the comfort and safety of the driver. The system is based on …

Smoking is widely recognized as a significant risk factor in the progression of arterial
stiffness and cardiovascular diseases. Valuable information related to cardiac arrhythmias …

Introduction: Current microvascular assessments may not be practical or accessible
requiring experienced personnel and/or ongoing equipment costs. Piezoelectric transducers …
