a Schematic representation of the single CNF on the MEMS substrate bonded on to a printed circuit board for wind tunnel test. b SEM micrograph of the nanoindenter tip positioned over an isolated CNF secured on a microfabricated substrate. c SEM micrograph of the isolated CNF stretched by the nanoindenter tip to demonstrate its stretchability. d Circuit schematic representing the data acquisition setup for the single CNF air flow sensor. e Plot showing the change in voltage across a single CNF in response to increasing wind flow velocity. Scale bars (b) = 100 µm; (c) = 10 µm.
