Conductive structures and flexible sensors having the same

A flexible sensor, comprising:

• at least one sensing structure, wherein each of the at least one sensing structure includes:
• two electrode plates which are disposed opposite to each other;
• and
• a dielectric flexible body disposed between the two electrode plates, the dielectric flexible body deforming under action of an external force to change electrical signals of the two electrode plates;
• wherein each of the two electrode plates includes a conductive structure, the conductive structure including:
• a substrate including an accommodation groove;
• a solid conductor at least partially accommodated in the accommodation groove, wherein the solid conductor and the accommodation groove form a first accommodation region, wherein the solid conductor includes a first conductor portion and a second conductor portion, the first conductor portion and the second conductor portion forming a step structure;
• and
• a fluid conductor filled in the first accommodation region and extending outside the accommodation groove, wherein a projection of a contact region of the fluid conductor and the solid conductor along a depth direction of the accommodation groove and a projection of the solid conductor along the depth direction have an overlapping region.
