Aim of the project
Respiratory monitoring is intensively used in medicine. It could be used in non-medical fields as well, such as sport, fitness, singer and wind instruments players training. Spirometry provides direct measurements of breathing volume, but require measurement device to be attached to the patient mouth, that is inconvenient to patient and hospital staff and prevents spirometry to be used for continuous monitoring in non-hospital environment. A number of techniques has been developed to replace spirometry, electrical impedance tomography (EIT) being one of them. The advantage of EIT is its ability to evaluate lung volume even regionally; rendering this method functionally superior to spirometry. EIT required an array of conventional bio-potential electrodes to be attached to the patient chest. The idea of the project is to replace conventional electrodes with ones made of conductive knitted textile. Textile electrodes could be easily integrated in a patient’s underwear, such T-shirts or bodies, herewith providing wearables to perform daily respiratory monitoring in hospitals, at home, during physical activity etc. in convenient way. Preliminary study at RTU demonstrated such electrodes as being capable to measure human bio-potentials, e.g. ECG or electromyogram. The goal of the present project is to demonstrate usability of textile electrodes for EIT measurements.
