Fig. 4 — (A) Schematic diagram of the synergistic mechanical and optical signal for mechano-photonic artificial synapse. (B) −ΔPSCs under different P_LED^’s at a fixed D of 1 mm, V_D = 1 V, and light pulse width of 0.5 s. Inset: The peak current of ΔPSC versus P_LED. (C) −ΔPSCs under different P_LED^’s when the light is turned off. (D) −ΔPSCs at different light pulse width (P_LED = 3.5 mW cm⁻² and D = 1 mm). (E) The −ΔPSCs under 40 consecutive light pulses under different displacements (P_LED = 3.5 mW cm⁻²; pulse width, 50 ms; D = 0.5, 1, and 1.5 mm). (F) The conductance margins (G_max/G_min) as a function of displacement.
