Tactile　Internet　can　be　seen　as　the　next　wave　of　innovation,　which　has　the　characteristics　of　low　latency,　high　reliability,　availability,　and　security.　Tactile　Internet　promises　its　application　in　various　fields　ranging　from　industry　automation　and　transport　systems　to　healthcare,　education,　and　gaming.　Therefore,　in　this　paper,　we　present　the　application　of　tactile　Internet　in　healthcare　by　considering　the　diabetic　ketoacidosis　(DKA)　as　a　use　case,　which　is　a　potentially　life-threatening　complication　of　diabetes　mellitus.　Severe　DKA　causes　Kussmaul　breathing,　which　is　a　life-threatening　condition　that　usually　requires　hospitalization.　However,　to　date,　no　real-time　monitoring　system　exists　for　DKA.　In　this　paper,　we　propose　a　nonintrusive　breathing　monitoring　system　using　the　C-Band　sensing　technique.　The　system　exploits　a　microwave　sensing　platform　to　capture　breathing-induced　chest　movements　in　diabetic　patients.　A　peak　detection　algorithm　is　used　to　acquire　the　respiratory　rate　and　extent,　identified　as　normal　breathing　or　Kussmaul　breathing.　The　real-time　respiratory　rate　and　extent　could　be　used　to　diagnose　DKA　in　diabetic　patients.　The　accuracy　for　all　the　subjects　are　99.76%,　98.69%,　97.82%,　99.06%,　and　98.42%,　respectively;　therefore,　the　reliability　of　the　system　is　demonstrated.　©　2019　IEEE.
