Agar/graphene conductive organogel with self-healable, adhesive, and wearable properties

Recently, advanced wearable electronic devices have shown great potentials for diverse applications in motion detection, human–machine interaction, and artificial intelligence. However, it is still a challenge to fabricate electronic materials with excellent adhesion and self-healing capability for the construction of various wearable electronic devices. Herein, we report an agar/graphene conductive organogel with excellent self-healing, adhesion and wearable properties. Among others, the adhesion of the agar/graphene conductive organogel is robust to a variety of substrates. The agar/graphene conductive organogel could also be rapidly self-healed based on hydrogen bonding which is triggered by the mechanical force or the near-infrared light irradiation. Furthermore, the agar/graphene conductive organogel can be utilized as the wearable device to detect the human motion and tiny physiological activities sensitively and reliably. We anticipate that the adhesive, self-healable and wearable agar/graphene conductive organogel may have promising potential in electronic wearable devices.
