Voluntary hand movements are usually impaired after a cerebral stroke, affecting millions of
people per year worldwide. Recently, the use of hand exoskeletons for assistance and motor …

Pulse waves (PWs) are mechanical waves that propagate from the ventricles through the
whole vascular system as brisk enlargements of the blood vessels' lumens, caused by …

Forcecardiography (FCG) is a novel technique that records the weak forces induced on the
chest wall by cardio-respiratory activity, by using specific force sensors. FCG sensors feature …

Seismocardiography (SCG) is largely regarded as the state-of-the-art technique for
continuous, long-term monitoring of cardiac mechanical activity in wearable applications …

Hand prostheses partially restore hand appearance and functionalities. In particular, 3D
printers have provided great opportunities by simplifying the manufacturing process and …

Electromyography (EMG) is widely used in human–machine interfaces (HMIs) to measure
muscle contraction by computing the EMG envelope. However, EMG is largely affected by …

The cardiac function is influenced by respiration. In particular, various parameters such as
cardiac time intervals and the stroke volume are modulated by respiratory activity. It has long …

Wearable devices based on surface electromyography (sEMG) to detect muscle activity can
be used to assess muscle strength with the development of hand rehabilitation applications …

Exoskeletons and other wearable devices benefit from sensor systems that are based on
biofeedback for detecting muscle activity. However, such sensor systems in wearable …

Force myography (FMG) represents a promising alternative to surface electromyography
(EMG) in the context of controlling bio-robotic hands. In this study, we built upon our prior …
