Fig. 5 Piezoelectric e-skin with interlocked microdome array for dynamic touch and acoustic sound detection. Piezoelectric e-skin with interlocked microdome array for dynamic touch and acoustic sound detection. (A) Piezoelectric output currents of e-skins with (top) interlocked microdome array and (bottom) single planar geometries. (B) Pieozoelectric pressure sensitivities of the e-skins fabricated with different materials and device structures (frequency of loading pressure, 0.5 Hz). (C) Piezoelectric output voltage and current under repetitive impact pressure loadings at different frequencies (0.1 to 1.5 Hz) for the static normal loading force of 8.56 kPa at a fixed pushing distance of pushing tester. (D) Schematic illustration of the sound detection tests using the piezoelectric e-skins at the sound intensity of 96.5 dB. The sensor distance from the speaker is 2 cm. (E) Variation of the piezoelectric voltage in response to acoustic waves of different frequencies. (F) The waveforms of acoustic sound for different letters of the alphabet (“S,” “K,” “I,” and “N”) (black). The readout voltage signals from the interlocked microdome (red) and planar e-skins (blue). (G) The waveform and short-time Fourier transform (STFT) signals of the original sound (“There’s plenty of room at the bottom,” black) extracted by the sound wave analyzer, readout signals from the interlocked e-skin (red), and microphone (blue).
