In Peru, 5.2% of all the population are people with motor disabilities. Some of these with
congenital malformations or forearm amputations suffer from difficulties within society to …

Over the years, researchers have studied the evolution of Electrocardiogram (ECG) and the
complex classification of cardiovascular diseases. This review focuses on the evolution of …

Electrooculography is a technique for measuring the corneo-retinal standing potential of the
human eye. The resulting signal is called the electrooculogram (EOG). The primary …

Novel dry electrodes are increasingly evolving for monitoring electrocardiograms compared
to the widely used Ag/AgCl (wet) electrodes as there is no skin preparation or wet gel …

This paper reports on a novel analog front-end circuit designed to measure light intensity
variations for portable/wearable and implantable sensor applications in different fields …

Surface electromyography (sEMG) monitoring has recently inspired new applications in the
