摘      要：Thermoelectric(TE)technologies offer a promising approach for directly converting skin heat into electricity for wearable *** p-type Sb2Tes and n-type BizTes as top-performing materials at room temperature,their rigid inorganic structure,with ultralow moisture permeability,poses challenges in warm and humid conditions,fostering bacterial growth and potential skin *** address this issue,we developed a cross-linked core-shell structure by electrodepositing Sb_(2)Te_(3)(Bi_(2)Te_(3))onto carbon fiber(CF).This architecture significantly improved the electrical conductivity and the Seebeck coefficient,resulting in a remarkable 300-fold increase in the power factor compared to that of pure *** CF/Sb_(2)Te_(3) and CF/Bi2Te films demonstrated optimal power factors of 450 and 121μW·m^(-1)·K^(-2),***,the fabricated films exhibited outstanding moisture permeability,over 3000 g·m^(-2)·d^(-1),exceptional electromagnetic interference shielding efficiency approaching 93 dB,and versatility as sensors for language assistance and respiratory *** attributes underline their broad applicability,emphasizing their suitability for human health protection in diverse scenarios.
