Keywords:magneticforceeffect,forcesensor,bypassstructure,sensitivity,hysteresis 1.Introduction Inrecentyears,magneticforceeffecttechnologyhasbeenwidelyappliedinthedevelopmentofforcesensors,whichcanprovidemoreprecisesensingcapabilitycomparedwithtraditionalmechanicalsensors[1,2].Magneticforceeffectsensorsutilizemagneticfieldvariationscausedbyexternalforcetodetectandmeasuretheforceappliedonthesensor,andtheyhavetheadvantagesofhighresolution,highaccuracy,andgoodlinearity.Therefore,theyarewidelyusedinvariousforcemeasurementapplications,suchasrobotics,aerospace,andbiomedicalengineering[3-5]. However,magneticforceeffectsensorsstillhavesomechallengesastheirperformanceisaffectedbyvariousfactors,suchashysteresis,drift,andresidualmagneticforces[6-8].Toimprovetheperformanceofthesensors,manyeffortshavebeenmade,suchasusingcompensationmethodstoreduceerrorscausedbytemperatureandnonlinearities,andoptimizingthesensorstructuretoenhancethesensitivityandstability[9-11].
