  Abstract: Elastomer-embedded phase change material (EPCM) composites are developed as stretchable, leakage-free, and electrically insulating thermal regulation layers for wearable electronics operating under stringent skin-safety requirements. The EPCM architecture comprises microencapsulated organic phase change materials (μPCM, 30–70 wt%) uniformly dispersed within soft elastomer matrices based on PDMS or SEBS-type thermoplastic elastomers, together with low loadings (1–8 wt%) of electrically insulating hexagonal boron nitride (h-BN) fillers to enhance lateral heat transport. Differential …
