Sensors,　functioning　as　primary　conveyors　of　perceptual　data,　stand　ready　to　illuminate　the　landscape　of　the　intelligent　era.　Barium　titanate,　an　exceedingly　pivotal　class　of　ferroelectric　materials　for　sensor　applications,　has　attracted　considerable　attention　from　both　commercial　and　industrial　sectors　in　recent　years.　Against　this　backdrop,　this　paper　embarks　on　a　comprehensive　examination　of　sensors　founded　upon　barium　titanate　across　a　spectrum　of　applications.　Our　investigation　commences　with　a　historical　analysis　of　ferroelectric　materials,　with　a　specific　emphasis　on　the　developmental　trajectory　of　barium　titanate.　Subsequently,　an　in-depth　exposition　elucidates　the　attributes　and　manufacturing　processes　linked　to　barium　titanate　materials,　providing　readers　with　insight　into　the　structural　and　manufacturing　aspects　of　these　materials.　Ultimately,　we　introduce　a　diverse　array　of　sensors　tailored　to　distinct　functions　within　a　myriad　of　domains.　With　the　progression　of　science　and　technology,　sensors　have　evolved　into　indispensable　components　within　the　domain　of　artificial　intelligence.　This　paper　primarily　undertakes　a　thorough　examination　of　sensors　utilizing　barium　titanate　across　a　spectrum　of　applications.　To　commence,　the　properties　and　preparation　of　barium　titanate　are　delineated,　succeeded　by　an　exploration　of　diverse　sensor　applications　and　the　prospective　developments.　image
