Inorganic flexible thermoelectric materials:Research prog-ress,optimization strategies and application prospects
摘要
Abstract
With the rapid development of wearable electronic devices,the Internet of Things,and portable medical monitoring systems,developing sustainable self-powered flexible power sources compatible with these technologies has become a research focus.Flexible semiconductor-based thermoelectric power generation technology,which utilizes the temperature difference between human body heat and the environment to directly convert it into electricity,provides a highly promising technical solution for achieving this goal.Although traditional inorganic thermoelectric materials possess excellent thermoelectric properties,their intrinsic brittleness severely restricts their practical application in flexible devices.In recent years,breakthrough progress has been made in the field of inorganic flexible thermoelectric materials through material design(e.g.,the discovery of intrinsically plastic inorganic semiconductors)and structural engineering(e.g.,the preparation of low-dimensional nanostructured films and fibers).This review systematically summarizes the representative works in this field.First,the basic principles and key performance parameters of flexible thermoelectric technology are elaborated.Second,the research status of important material systems is highlighted,including silver chalcogenides,bismuth telluride-based materials,carbon nanotube-based composites,and emerging plastic inorganic semiconductors(e.g.,SnSe2,Bi).Subsequently,the application examples of these materials in fields such as wearable energy harvesting,solid-state cooling,and sensing are discussed in detail.Furthermore,the synergistic optimization strategies for enhancing both the thermoelectric performance and mechanical flexibility of materials are analyzed in depth,including band engineering,defect engineering,microstructure regulation,and composite material design.Finally,the main challenges currently faced in the field of inorganic flexible thermoelectrics are examined,and prospects for their future development directions are presented.关键词
