In this study, paraffin wax (PW) was combined with fumed silica (FS) as a porous support and Fe3O4-incorporated expanded graphite (EG@Fe3O4) thermal conductivity enhancer multifunctional conversion agent. This combination resulted in the development of PW/FS/EG@Fe3O4 composite phase change materials (CPCMs) varying PW content (60-80%). FS provided ample space to stabilize significant amount (up 75%) without liquid leakage. The crystallization fractions confined exceeded 97%, outperforming most reported values for other PCMs SiO2-based enabling high enthalpies (e.g., 146.1 J g-1 75% PW). conductivities 60-80% CPCMs were significantly enhanced 2.215-1.395 W (m K)-1, representing an increase 9.8-6.2 times compared pristine PW. Additionally, EG@Fe3O4 endowed electrothermal magnetothermal capabilities due electrical EG superparamagnetism Fe3O4. Experimental testing demonstrated its ability exceed melting point under application either DC voltage or alternating magnetic field. When used heat pack, CPCM maintained consistent release within 50-55 °C range 12 minutes on volunteer's back, meeting surpassing requirements high-temperature thermotherapy. Overall, conductivity, substantial enthalpy, excellent cycling durability, makes highly promising practical thermotherapy applications.

Abstract Flexible electronics are of great interest in wearable bioelectronics, biomedicine, and robotics, with hydrogel emerging as an ideal candidate due to its excellent biocompatibility, stretchability, flexibility, making it suitable for applications electronics, clinical medicine, soft robotics. However, traditional hydrogels limited by restricted application scenarios, poor controllability, insufficient smart responsiveness. In contrast, phase transition hydrogels, characterized their reversible properties multifunctional adaptability, represent a promising advancement flexible electronics. This review systematically examines the various reaction types detailing underlying mechanisms materials involved. Furthermore, principles optical devices analyzed. Additionally, roles thermal management robotics explored. Finally, prospects challenges hydrogel‐based discussed, emphasizing need further optimization molecular structure cross‐linking system design, precise tuning temperature rate, enhancement long‐term stability, seamless integration conventional silicon‐based
