Research progress in flexible wearable pressure sensors based on electrospinning nanofibers

The flexible wearable pressure sensor has uniquepropertiessuchashighcomfort,strong braidabilityandtheabilitytoimitate human skintosensitively perceiveandrespondto external stimuli.It can be used asthe artificialelectronic skin which will be widely appliedin medical detections,diseasediagnosis,human motiontrackingandhealth monitoring,etc.Inrecentyears,the design,construction,performanceexplorationanddevelopmentofflexible wearablepressuresensors have attracted extensive attention from researchers. The nanofibrous membranes prepared by electrospinninghavethe advantages of high porosity,large specific surface area and easyto be functionalized,which makethem haveextensiveapplicationsinthefield offlexiblesensors.The researchandprogressofelectrospunnanofibersinflexiblewearablepressuresensorswerereviewedin thispaper.Themajorcharacteristicsofthewearablepressuresensorswerebrieflyintroduced,andthe advantagesofelectrospinningtechnologyandelectrospinningnanofibersinthepreparationofflexible wearablepressuresensorsweredescribed.Thetypesandapplicationsoftheflexiblewearablepressure sensorsbasedonelectrospinningindifferentfieldswereemphaticallydiscussed.Finally,thelow-cost manufactureofflexible wearablepressuresensorswithhighresolution,highsensitivityandaccurate response was briefly summarized and prospected.
