Wearable Device for Yogic Breathing

Yogic breathing or pranayama refers to various breathing exercises where we control our breathe. These breathing techniques vary in complexity. Often, the individual practices yogic breathing by three-part breath in which they inhale, then hold the breath for particular duration and finally exhale. This way they deepen their breathing and bring it under control. Further they may learn more advanced yogic breathing techniques, such as `Kapalabhati'. All of these have their own unique benefits and effects on the body and mind when practiced systematically. Since these techniques rely on systematic breathing there is a need for a device which can monitor breathing and aid in performing these techniques in the right manner. The paper discusses about design and testing of a wearable device that can monitor heart rate, posture and yogic breathing. The device is tested on different subjects with various breathing exercises to verify the data obtained and its significance.
