Flexible sensing device, sensing system and application thereof

The invention relates to the technical field of materials, in particular to flexible sensing equipment, a sensing system and application thereof. The flexible sensing device comprises a flexible substrate layer, a flexible circuit layer and a protective layer which are sequentially arranged in a stacked mode. A silk protein film is arranged on the bottom surface of the flexible substrate layer; the bottom surface of the flexible substrate layer is attached to a to-be-assembled object; the flexible circuit layer comprises a flexible circuit board and at least two sensing devices located on the flexible circuit board; the at least two sensing devices are electrically connected with the processing equipment respectively; the sensing device comprises a pressure sensor and an environment detection sensor; the protective layer comprises an opening which is used for exposing at least two sensing devices; and a silk protein film is arranged on the outer surface of the protective layer. Therefore, the attaching streng
