Abstract :
This paper reports a novel method for digital sensing of low-velocity air flow using high aspect-ratio 3D printed conducting polymer (PEDOT:PSS) micro-hair structures (1000 μm long, 5.5±0.5 μm diameter). By implementing multiple micro-hair structures as micro-switches that respond to air flows of particular velocities, a low-velocity digital flow sensor capable of detecting air flow in the range of 61 mm/s to 99 mm/s is demonstrated.
