Fig. 3

a Schematic illustration of optoacoustic signal propagation. b Theoretical (dotted line) and experimental (solid line) results of acoustic pressure as the change of PDMS II layer thickness. The black, red, blue, and pink curves represent the acoustic pressure results for PDMS thickness of l = 30, 15, 10, and 5 μm, respectively. c The amplitude of optoacoustic pressure at different light intensities. The black, red, blue, and pink curves represent the acoustic pressure under the light intensity of 3, 2, 1.3, and 1 mJ pulse−1, respectively.
