With the advancement of technology and the growth of market demand,smart wearable technology is developing rapidly.Smart wearable electronic devices(including electronic skin,sports wristbands,smart watches,etc)are becoming more and more popular in people's daily life.At present,smart wearable devices are gradually developing towards flexibility,light weight and portability,and they need to meet the characteristics of softness and comfort,flexibility and lightness,and fit the human body well.Textile materials are found everywhere in people's daily life and can be classified according to their form into fibers,yarns and fabrics,subsequently utilized in various textile processing techniques to manufacture various garments and textile products.At different stages of the manufacturing of processing textiles,fibers and yarns have been defined as one-dimensional horizontal structures and fabrics as two-dimensional or three-dimensional horizontal structures.Now various methods have been proposed to endow them with conductive sensing properties to build wearable and flexible sensor devices to play an important role in fields such as sports,health care,and human-computer interaction.One-dimensional structured flexible sensors have the advantages of less integration difficulty,more excellent conformability,flexibility and stretchability,and greater malleability compared to non-one-dimensional sensors,allowing for low-cost processing and continuous production.At present,the research on one-dimensional structured flexible sensors has made significant progress,including the perception of temperature,pressure,stretching and optical changes,and the monitoring of object shape,human movement posture,health status and other functions of the sensor.Some researchers have produced electronic skin,smart clothing and smart textile products by processing them with existing knitting and weaving technologies,which has shown great development potential in developing different smart products.Therefore,one-dimensional structured wearable flexible sensors need to be further studied in depth and a series of smart products such as smart textiles,smart clothing and smart wearable devices can be developed through continuous production with existing mature processing technologies.In addition,the possibility of use of one-dimensional structured flexible sensors to build functions including sensing,actuation,and communication has been proven by researchers.In the future,it will promote the advancement of scientific research in the direction of flexible circuits,fabric antennas,multifunctional sensors,etc.,and it has become a research hotspot to research and develop flexible one-dimensional structured sensors and to expand the scope of their comprehensive applications.In summary,as an important branch of flexible sensor devices,wearable flexible sensors with one-dimensional structure have been favored in the fields of wearable technology,health monitoring,and smart electronic skin,and have also gradually integrated into people's daily life to provide convenience.There is no uniform testing standard for the performance of flexible electronics products,which is still a challenge for researchers in their research work.At present,it is necessary to continuously enhance and improve the functionality and practicality of the products to promote the development of wearable flexible sensors with one-dimensional structure in the field of smart wearables.The future endeavor to design one-dimensional structured sensors with high sensing efficiency,multi-modal functionality,and stable performance requires mutual cooperation among researchers in various fields of textile engineering,electronic information,and materials science to promote scientific and technological innovations,and to bring more convenience to people's life and work.
