Recap on bio-sensorial stress detection methods and technology

Abstract

Mental stress consist in a biological condition that allows reaction to a demand or unknow situation, it is a necessary aspect for survivable, but, in a big among can turn into acute stress and if acute or common stress is not treated can become chronic stress a very dangerous health condition which can also be trigger for several cardiac disorders like heart attack or even strokes, for the las 20 years stress has increase severely due to our new lifestyle, this document gives a complete recap of stress detection by showing characteristics, health consequences and types of stress, as well as, recollect a background of previous research from methodologies like machine learning implementation to complex sensorial analysis, impacts and advances in stress detection, it also contain general concepts needed to obtain a full compression of stress detection, explanations of EDA (Electrodermal activity), cardiovascular activity, muscular activity, respiratory response, etc. follow by an explanation of devices capable of read such signals using GSR (Galvanic skin reflection), PPG(Photo plethysmography), EMG(Electromyogram), ECG(Electrocardiogram), etc. in addition, the proposed of a comparative table between all the common stress detection techniques, emphasizing parts of the body in which a lecture can be obtain, advantage and disadvantages of each signal and common application, equally important a new classification for stress detection methods.
