Advancing textile thread transducers for airflow measurement and characterization
Résumé
This paper presents the fabrication and testing of a new stretchable transducer that can undergo stretching ratio up to 600%without losing its electrical conductivity. The transducer is a functionalized textile fiber exhibiting high elasticity with a Young's modulus of 5.1 Mpa. The transducer under low force application has a gauge factor ranging from 0.24 to 9.17 when stretched between 5% and 100%, respectively, showing a good sensitivity over a wide range of deformation. This is achieved without degradation of the material as shown by the absence of delamination of the conductive layer, even after a 600% stretch. All these properties make this transducer suitable for smart textile applications.
