  • Patent number: 10816418
    Abstract: A three-layer self-healing flexible strain sensor includes: a self-healing sensitive layer, wherein a self-healing encapsulating layer is respectively placed on an upper surface and a lower surface of the self-healing sensitive layer. The self-healing sensitive layer comprises a doped carbon material or a conductive composite. The three self-healing layers of the self-healing strain sensor can quickly repair the internal and external damage caused by the layered structure in a short period of time after the external damage, and does not require external stimulation. The three-layer self-healing structure strain sensor is simple in preparation without using a repair agent, which can achieve rapid self-repair at the room temperature, and can be repeatedly repair. The three-layer self-healing structure increases the strength and modulus of the strain sensor as well as increases the ability of the strain sensor to resist external damage.
