<p>Wearable sensors are smart electronic devices extensively investigated for use in watches, patches, fabrics, among other applications attached to the body. They monitor, analyze, and transmit physiological and physical data in real time. In this sense, new and innovative materials have been developed aiming to focus on sustainability, intelligence, and high performance. Key breakthroughs include the application of carbon dots in supercapacitor using self-healing elastomers. The incorporation of carbon dots in supercapacitor is used to improve the energy density of supercapacitors while the elastomer can bear high deformations without losing performance. Therefore, with an emphasis on the previous teen years, this paper provides a systematic review of wearable sensors containing a self-healing elastomer matrix using carbon dot based- supercapacitors. In order to answer a research question, the study adhered to the PRISMA protocol, which provides a thorough summary of all available primary research. Nineteen studies were included in the review after the inclusion/exclusion of steps. The findings were centered on the rheological, thermal, mechanical, biological, and electrical characteristics. In summary, this approach assisted in determining the primary knowledge gaps.</p>
