Textile Thread Piezoresistive Transducer for Airflow Characterization
The development of a piezoresistive thread for characterizing airflow in the vicinity of filters implemented in Heating, Ventilation and Air Conditioning (HVAC) systems is presented. These threads exhibit a sensitive response with a gauge factor of 25 over 10000 cycles of elongation at 5% strain. The thread is then integrated in a laboratory scale ventilation duct to demonstrate that it can discriminate airflow speed between 1 and 3 m.s<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup>, which is within the range of interest of HVAC systems.
