Overview of the flexible and transparent Maya pyramid pressure sensor: (a) SEM image of the Maya pyramid structure ITO. Inset shows a zoomed-in image. The scale bar is 1 mm. (b) Schematic image of each Maya pyramid structure pressure sensor. (c) Electrical characteristics of the pressure sensor as a function of the applied pressure with various layer structures. (d) Response times of the pressure sensor. (e) Endurance test results of the pressure sensor under 1k Pa. (f) Reproducibility of the electrical properties at various pressures.
