Abstract Understanding the behavior of confined matter within Van der Waals (VdW) materials is complicated due to interplay various factors, including VdW interaction between interlayers, layer with matter, and bending strain energy layers accommodate encapsulation. Herein, new insight on magnitude pressure density water entrapped spaces in provided. This accomplished by studying plasmon excitation encapsulated two sheets graphene membranes an aberration‐corrected scanning transmission electron microscope. The results indicate ≈12% maximum increase under tight encasement, where as high 400 MPa expected. estimation from theoretical analysis considering effect forces, Laplace pressure, agreement experimental results. findings this work open opportunities explore local physical state not only but also other liquid imaging analytical resolutions never achieved before.
