Fig. 5: Strain field reconstruction with our sensing film in different deformation states.
From: High-density, highly sensitive sensor array of spiky carbon nanospheres for strain field mapping
a The surface is subjected to homogeneous uniaxial stretching (FEA: finite element analysis). b The tested object has a gradient thickness and is subjected to uniaxial stretching. c The sensing film is used to detect the strain distribution near a crack tip. All these test data were collected by a sensing array with a scale of 30 × 30 and a density of 100 pixel cm−2. Source data are provided as a Source Data file.
