Textronic sensors of respiratory rhythm frequency

Abstract

In the work the construction of textronic sensors for measuring respiratory rhythm frequency. Sensors have a textile structure, since they were made from piezoelectric, optical waveguide and electroconductive materials. Sensors were placed in a measuring shirt. A piezoelectric tortuous sensor was sewn into the shirt; similarly, an optical fibre was placed in the shirt. A sensor of electroconductive fibres was made in the form of knitted fabric. The sensors were tested on measuring positions and patients. The characteristics of the sensors and the curves of input voltages of the sensors have been presented. The correctness of operation of the sensors was verified by the measurements obtained by means of a professional spirometer.
