摘要
We report the creation of a low flow rate sensor from PEDOT micro-hairs. The hairs are printed as pipette-defined depositions using a nanopositioning system. The printing technique was developed for fabricating structures in 2D and 3D. Here micro-hairs with diameters of 4 : 4 mu m were repeatedly extruded with constant heights. These hairs were then applied to produce a prototype flow rate sensor, which was shown to detect flows of 3 : 5 l min(-1). Structural analysis was performed to demonstrate that the design can be modified to potentially observe flows as low as 0 : 5 l min(-1). The results are extended to propose a practical digital flow rate sensor.
