1 Introduction The rapid growth of flexible electronics and wearable technology has created a strong demand for lightweight, flexible, resource-efficient, and mechanically compliant energy harvesting technologies [1-7]. Among different approaches, triboelectric nanogenerators (TENGs) have emerged as a promising solution due to their ability to easily convert mechanical energy to electrical energy through contact electrification and electrostatic induction [8-18].

Sustainable Castor Oil-derived Cross-linked Poly(ester-urethane) Elastomeric Films for Stretchable Transparent Conductive Electrodes and Heaters Substrates are essential for flexible and stretchable devices, requiring sustainability, stretchability, transparency, thermal stability, and chemical stability.

1. Introduction Breast augmentation is a widely utilized cosmetic procedure, with approximately 193,000 procedures in the United States alone in 2020 [1]. Despite being a standard procedure, it has associated complications, ranging from common complications like bleeding, infection, seroma, and hematoma formation to more severe outcomes such as skin necrosis, Mondor disease, capsular contraction, and implant rupture [2,3,4,5,6,7].
