Paragraph starter

The development of advanced epidermal electronics for health monitoring necessitates careful consideration of human factors, particularly thermal comfort. Research by Peng et al. (2024) highlights that by incorporating thermally conductive materials, such as those enhanced with nanoparticles, into electronic textiles, significant improvements in heat dissipation can be achieved (0.72 W m−1 K−1). This directly addresses the issue of heat accumulation, a common constraint that can limit the prolonged wearability and user acceptance of skin-attachable devices. Therefore, integrating effective thermal management strategies into the design of wearable health monitors is crucial for enhancing user experience and ensuring the practical application of such technologies.
