Distribution of the instant radial pressure on the vesicle surface and its dependency on the media conductivities. A. Radial pressure compressed the cell if the extracellular conductivity was greater than intracellular conductivity (σ _o  = 1.2S/m, σ _i  = 0.3S/m). B. Radial pressure stretched the cell if the intracellular conductivity was greater (σ _i  = 1.2S/m. σ _o  = 0.3S/m). The color represented the amount of the charge density (C/m²) calculated with the parameters in Table 1. Field frequency was 10 KHz.
