Abstract
A strain sensor is disclosed. The strain sensor includes: a base provided with a mounting recess; a mounting structure disposed on the base and located in the mounting recess, a preset gap being formed between the mounting structure and an inner surface of the mounting recess; a bearing structure mounted in the mounting recess and located outside the preset gap; and a wire set of a plurality of electrically conductive wires, at a side of the wire set each of the wires being fixedly disposed on the bearing structure, and at another side of the wire set each of the wires being fixedly arranged on the mounting structure to detect strain based on change of resistance of the wire set by a load applied through the bearing structure on the wire set.
