The flexibility in polymer properties has allowed the development of a broad range materials with electroactivity, such as intrinsically conductive conjugated polymers, percolated composites, and ionic hydrogels. These smart electroactive polymers can be designed to respond rationally under an electric stimulus, triggering outstanding suitable for biomedical applications. This review presents general overview potential applications these field tissue engineering biomaterials. In particular, details about ability to: (1) stimulate cells context by providing electrical current; (2) mimic muscles converting energy into mechanical through electromechanical response; (3) deliver drugs changing their internal configuration stimulus; (4) have antimicrobial behavior due conduction electricity, are discussed.

Abstract Chronic wounds are a major health concern and they affect the lives of more than 25 million people in United States. They susceptible to infection leading cause nontraumatic limb amputations worldwide. The wound environment is dynamic, but their healing rate can be enhanced by administration therapies at right time. This approach requires real‐time monitoring with on‐demand drug delivery closed‐loop manner. In this paper, smart automated flexible dressing temperature pH sensors integrated onto bandages that monitor status address unmet medical need presented. Moreover, stimuli‐responsive releasing system comprising hydrogel loaded thermo‐responsive carriers an electronically controlled heater also into release drugs on‐demand. equipped microcontroller process data measured program protocol for individualized treatment. has potential significantly impact treatment chronic wounds.

Abstract Injectable hydrogels have received considerable interest in the biomedical field due to their potential applications minimally invasive local drug delivery, more precise implantation, and site‐specific delivery into poorly reachable tissue sites interface tissues, where wound healing takes a long time. hydrogels, such as situ forming and/or shear‐thinning can be generated using chemically physically crosslinked hydrogels. Yet, for controlled applications, ideal injectable hydrogel should able provide sustained release of molecules target site when needed limit nonspecific molecule distribution healthy tissues. Thus, sense environmental changes that arise disease states optimal amount over necessary time period region. To address this, researchers designed stimuli‐responsive Stimuli‐responsive change shape or volume they stimuli, e.g., pH, temperature, light, electrical signals, enzymatic changes, deliver an concentration drugs without affecting
