Effect of (a) sound wave frequency, (b) SPL (sound wave frequency, 220 Hz), (c) hole profile on device voltage outputs. Effect of (d) hole diameter (web thickness, 40 μm; sound wave frequency, 220 Hz; SPL, 115 dB), (e) thickness of the nanofibre web (hole diameter, 12.8 mm; sound wave frequency, 220 Hz; SPL, 115 dB), (f) nanofibre web area (hole diameter, 12.8 mm; web thickness, 40 μm; sound wave frequency, 220 Hz; SPL, 115 dB) on device sensitivity. The error bars represent the s.d. of the test results of at least three replicates.
