The invention refers to a flexible pressure or strain mapping device comprising a fibrous substrate layer (1), which comprises at least a layer zone impregnated with a hydrogel (2); a first sensor electrode (3) having a portion contacting at least a lower part of said layer zone impregnated with a hydrogel (2); a second sensor electrode (4) having a portion contacting at least an upper part of said layer zone impregnated with a hydrogel (2).

The flexible pressure or strain mapping device comprises hydrogels that are flexible, and have higher performance regarding mechanical and sensing properties, considering that said materials are easily tuned, so they can be stretchable and biocompatible and may show self-healing properties.

Furthermore, the flexible pressure or strain mapping device can be arranged in arrays, to map a pressure distribution and provide a more precise output in several applications.
