The  research  forecastsan  exponential  growth  in  the  kidney  failureduring coming  years.There  are  twoconventional  treatments  for  end  stage  renal  disease  (ESRD) and  acute  renal  failure  (ARF)  those  are  dialysis  and  inherent  kidney  transplant.After kidney  transplant,the  patient  has  to  take  expensive  medicine  for  a  long  time.There  are many  limitations  associated  with  the  conventional  treatment  methods.  To  overcome  the limitations  of  conventional  treatment  methods, MEMSbased  hemodialysis  machine  or wearable artificial kidney (WAK) can beused.Themajor benefit of this technology is that thepatients can continue  their  work  during  dialysis.  It  isvery  cheap  and  easy  to  operate.The basic objective of this research is to study the flow rate of available micropumps using different  liquids  (DI  water,  heparin,  blood,  etc)  and  find  out  the  suitabledevice  forwearable  artificial  kidney  (WAK)or  hemodialysis  machine.The  controlled  electronic circuit  is  used  to  investigate  the  fluid  flow  rate  through  the  micropump.  The  sine  wave, rectangular  wave  and  SRS  signal  have  been  used  to  operate  the  micropump.  Numerical simulation of diaphragm of micropump has also been conducted using ANSYS tofind the deflection  and  stress  distribution  of  membrane.  This  study  gives  useful  information  to develop the MEMSbased hemodialysis system. 0aMicroelectronmechanical systems 0aAcute renal failurexTreatmentxComputer simulation1 aAfzulpurkar, Nitin V.,eChairperson0 aManukid Parnichkun,eExamination Committee0 aMongkol Ekpanyapong,eExamination Committee2 aUniversity of Balochistan, Quetta, Pakistan,eScholarship donor2 aAsian Institute of Technology Fellowship,eScholarship donor2 aAsian Institute of Technology.tThesis ;vno.
