Mechanical characterization of the device.
(A) Example of a particle-loaded membrane used for the device characterization. A matrix of 5 × 5 points of reference was tracked during the mechanical stimulation. (B) Strain map at different vacuum levels with the identified matrix. εyy, εxx, and εxy are strains in the direction perpendicular to the channel, parallel to the channel and shear strain, respectively. (C) Calibration curve showing vacuum level versus the resulting strain values. Data are expressed as means ± SD.
