(A) Under US effect the membrane starts fluctuating around a steady state. (B) Mechano-electrical dynamics of the model membrane to US (pressure amplitude 500 kPa and frequency 0.5 MHz): The increase in Acoustic pressure induces an increase in attraction/repulsion force, which increases the capacitance leading finally to a capacitive current. Acoustic pressure (kPa), tension (mN/m), combined attraction/repulsion force per area between the leaflets (sum of molecular and electrostatic forces, kPa), membrane capacitance (μF/cm²), and capacitive displacement current (A/cm²) [modified, under the terms of the Creative Commons Attribution 3.0 License, from Plaksin et al.
