Summary: This study conducted constant moisture stress-accelerated degradation tests on silicone encapsulant with different thermal stresses, and predicted its real lumen decay and color shift lifetimes by integrating the accelerated lifetime model with the Gamma process model. The results showed that the degradation rate of silicone encapsulant is related to thermal stress, and the prediction accuracy varies when using lumen decay lifetime versus color shift degradation data.

Summary: In this study, the effects of a hybrid filler composed of zero-dimensional spherical AlN particles and two-dimensional BN flakes on the thermal conductivity of epoxy resin were investigated. The results showed that the composite exhibited a 46-fold increase in thermal conductivity with the 75 wt% loading of the AlN-BN hybrid filler, along with higher thermal stability and lower coefficient of thermal expansion compared to pure epoxy.

Summary: This study reports a strategy to enhance the thermal resistance of silicone resins by introducing zirconium into the main chain. The molecular simulation shows that the introduction of zirconium atoms leads to the formation of high energy zirconium-oxygen bonds, increasing the cross-linking degree and suppressing the formation of cyclic oligomers. The results suggest that this work could provide a systemic experimental and theoretical foundation for thermal properties enhancement through metal atoms incorporation.

Summary: By coordinating Zr4+ with Ph-O- in phenolic resin, Zr chelated hybrid phenolic resin (ZrPR) with enhanced thermal stability was obtained. ZrPR reduced the content of Ph-OH in phenolic resin and provided a metal-organic chelated point, resulting in improved ablation resistance. Carbon fiber reinforced ZrPR composites (CF/ZrPR) exhibited higher strength and lower thermal conductivity and ablation rate compared to unmodified composites (CF/PR).

Summary: Ecoflex is widely used in bioelectronics due to its low modulus and large stretchability. Conventional patterning strategies for Ecoflex lack sufficient quality and process compatibility, so we propose a method of patterning Ecoflex by developing Photo-patternable Ecoflex (PPE). The PPE layer effectively dissipates strain energy, resulting in increased electrical conductance under strain. We fabricated intrinsically stretchable multi-sensors using PPE, which can monitor bio-signals in sweat and maintain durability under strain.
