(color online) (a), (b) Schematic illustration of the experimental design for the actuation. The CNT/PVDF composite strip is suspended between two bulged stages on the glass substrate. A laser displacement sensor is placed perpendicularly above the middle part of the strip to measure the actuation. (c), (d) Optical photograph of the CNT/PVDF composite strip (c) before and (d) after actuation. The driven voltage in panel (d) is 0.65 V and the displacement is .
