The concept of flexible hydraulic reservoir (FHR): (a) The sample is pumped by the pressure applied to the actuating fluid (blue); (b) The sample is delivered without any dead volume; (c) Acoustofluidic flexible micropump. The piezo ring that provides the excitation for the flexible layers; (d) Cell trapping with the micropump.
