柔性红外光电传感器的设计策略与研究进展

Infrared optoelectronic sensing is the core of many critical applications such as night vision,health and medication,military,space exploration,etc.Further including mechanical flexibility as a new dimension enables novel features of adaptabil-ity and conformability,promising for developing next-generation optoelectronic sensory applications toward reduced size,weight,price,power consumption,and enhanced performance(SWaP3).However,in this emerging research frontier,chal-lenges persist in simultaneously achieving high infrared response and good mechanical deformability in devices and inte-grated systems.Therefore,we perform a comprehensive review of the design strategies and insights of flexible infrared optoelec-tronic sensors,including the fundamentals of infrared photodetectors,selection of materials and device architectures,fabrica-tion techniques and design strategies,and the discussion of architectural and functional integration towards applications in wearable optoelectronics and advanced image sensing.Finally,this article offers insights into future directions to practically real-ize the ultra-high performance and smart sensors enabled by infrared-sensitive materials,covering challenges in materials devel-opment and device micro-/nanofabrication.Benchmarks for scaling these techniques across fabrication,performance,and inte-gration are presented,alongside perspectives on potential applications in medication and health,biomimetic vision,and neuro-morphic sensory systems,etc.
