Abstract Peripheral nerve regeneration and functional recovery is a major challenge in clinical practice. Nerve conduit an effective treatment for peripheral repair, but the traditional hollow not satisfactory repair due to limitation of cell migration nutrient transport. Herein, double cross‐linked hydrogels with injectable, self‐healing, conductive properties are synthesized by Schiff base reaction between polyaniline‐modified carboxymethyl chitosan aldehyde‐modified Pluronic F‐127 (F127‐CHO), hydrophobic interaction F127‐CHO. The hydrogel injected into cavity prepared electrodeposition. inner outer formed whole through obtain double‐layer composite conduit. neural loaded 7,8‐dihydroxyflavone (DHF) has excellent degradability, biocompatibility, antioxidant activity, Schwann proliferation activity. In rat sciatic defect model, significantly promotes compared Surprisingly, ability double‐layered DHF comparable that autologous transplantation. Therefore, this multifunctional great potential repairing.

Electrical stimulation can effectively accelerate bone healing. However, the substantial size and weight of electrical devices result in reduced patient benefits compliance. It remains a challenge to establish flexible lightweight implantable microelectronic stimulator for regeneration. Here, we use self-powered technology develop an electric pulse without circuits batteries, which removes problems weight, volume, necessary rigid packaging. The fully defect (BD-ES) system combines hybrid tribo/piezoelectric nanogenerator provide biphasic pulses response rehabilitation exercise with conductive bioactive hydrogel. BD-ES enhance multiple osteogenesis-related biological processes, including calcium ion import osteogenic differentiation. In rat model critical-sized femoral defects, was reversed by therapy subsequent mineralization, femur completely healed within 6 weeks. This work is expected advance development symbiotic batteries circuits.
