摘      要:Photothermoelectric(PTE)detectors functioning on the infrared spectrum show much potential for use in many fields,such as energy harvesting,nondestructive monitoring,and imaging *** advances in low-dimensional and semiconductor materials research have facilitated new opportunities for PTE detectors to be applied in material and structural ***,these materials applied in PTE detectors face some challenges,such as unstable properties,high infrared reflection,and miniaturization ***,we report our fabrication of scalable bias-free PTE detectors based on Ti3C2 and poly(3,4-ethylenedioxythiophene):polystyrene sulfonate(PEDOT:PSS)composites and characterization of their composite morphology and broadband *** also discuss various PTE engineering strategies,including substrate choices,electrode types,deposition methods,and vacuum ***,we simulate metamaterials using different materials and hole sizes and fabricated a gold metamaterial with a bottom-up configuration by simultaneously combining MXene and polymer,which achieved an infrared photoresponse ***,we demonstrate a fingertip gesture response using the metamaterial-integrated PTE *** research proposes numerous implications of MXene and its related composites for wearable devices and Internet of Things(IoT)applications,such as the continuous biomedical tracking of human health conditions.
