- Abstract
- A smart-fabric sensor for health monitoring has been fabricated using composite of single-walled carbon nanotubes (SWCNTs)-filled binary polymer of poly vinylidene fluoride/poly (3,4-ethylenedioxythiophene)-poly (styrenesulfonate) (PVDF/PEDOT:PSS). The response curves and working principle were investigated, and sensors were fabricated to achieve a highly linear and stable response for a wide range of temperatures (25-100 degrees C) and bending angles. The sensors show a stable and nearly linear response of impedance change by varying temperatures in the range of 25-100 degrees C. The impedance of the sensors changed from 5.8 M Omega to 2.95 M Omega for temperature change in the range of 25-100 degrees C with a sensitivity of 38 k Omega/degrees C. The bending movement sensitivity of the sensors was found to be 90 k Omega per degree angle, and the response of the sensor was very stable in the range of 0-120 degrees.
