Polymer systems that combine electrical conductivity with biodegradability are gaining attention for biological and medical uses. These materials satisfy the key requirement of compatibility with biological environments. Alongside their ability to degrade safely, they provide several practical advantages, including chemical stability in varying physiological conditions and straightforward processing that allows them to be fabricated into diverse forms. They also benefit from low manufacturing costs, making them viable for broad deployment. Their intrinsic electrical conductivity enables specialised functions within medical technologies. Areas of use for these biodegradable conducting polymer composites include tissue engineering, biomedical implants, and antibacterial formulations.
Medical devices and implants often require functional properties like electrical conductivity while remaining safe for the human body. Developing materials that conduct electricity, break down safely over time, and remain affordable to manufacture can support the development of better implants and therapies that naturally integrate into biological environments without requiring secondary removal procedures.
The material systems could enable commercial applications in tissue engineering scaffolds, medical implants, and antibacterial products. Developers and manufacturers in medical devices and biomaterials could utilise these polymers due to their processability and low production costs. Based on this review of ongoing work, the technology represents early to intermediate stage research exploring potential functional avenues rather than finished, market-ready medical products.

In recent years, researchers have increasingly directed their focus toward the biomedical field, driven by the goal of engineering polymer systems that possess a unique combination of both electrical conductivity and biodegradability. This convergence of properties holds significant promise, as it addresses a fundamental requirement for biomedical applications: compatibility with biological environments. These polymer systems are viewed as auspicious biomaterials, precisely because they meet this critical criterion. Beyond their biodegradability, these materials offer a range of advantageous characteristics. Their exceptional processability enables facile fabrication into various forms, and their chemical stability ensures reliability in diverse physiological conditions. Moreover, their low production costs make them economically viable options for large-scale applications. Notably, their intrinsic electrical conductivity further distinguishes them, opening up possibilities for applications that demand such functionality. As the focus of this review, a survey into the use of biodegradable conducting polymers in tissue engineering, biomedical implants, and antibacterial applications is conducted.
