Wearable sensors and feedback system to improve breathing technique

Abstract

Breathing is an important factor in our well-being as it oxygenates the body, revitalizes organs, cells and tissues. It is a unique physiological system in that it is both voluntary and involuntary. By breathing in a slow, deep and regular manner, the heartbeat become smooth and regular, blood pressure normalizes, stress hormones drop, and muscles relax. Breathing techniques are important for athletes to improve performance and reduce anxiety during competitions. Patients with respiratory illnesses often tend to take shallow short breaths causing chest muscle weakness, reduced oxygen circulation, shortness of breath and fatigue. Proper breathing exercises can help to reduce these symptoms as well as strengthen muscles, improve posture and mental ability. This work presents a wearable system which monitors breathing technique and provides straightforward feedback to the user through a graphical interface
