PIEZOELECTRIC GENERATOR POWERING THE PACEMAKER Kaushik Illa #36730160  [email protected]   Krishna Chaitanya Nutukirthi #36727542  [email protected]  Satya Prasad Akkina #36561674  [email protected]  Abstract The   piezoelectric   micro   power   generator  (PMPG)   is   fabricated   with   the   latest  technological material PZT on the Si substrates.  The wireless sensor nodes are to be placed on  the   motor   for   monitoring   the   power   flow   and  other electrical quantities. The energy generated  by PMPG can be rectified and this energy is  stored by  Schottky diode rectifier and custom  ANSI circuit. This generated  energy  from  the  PMPG is used to power the pacemaker and this  product would drive away the need to monitor as  well as replace the batteries periodically. 1. Introduction          The developments of Self Powered Micro  Systems   are   commonly   used   as   nodes   in  wireless sensor networks, which require small  size  and  extended autonomy. Since usage  of  batteries   does   not   last   long   MEMS   power  generators are used to generate power using  piezoelectric   effect   which   convert   mechanical  vibrations into useful electrical energy. But these  generators   produce   very   minute   voltage   of  200mV  which  is  boosted  and  amplified  using  Voltage   Multiplier   and   Rectifiers.   These  generators can be used to generate continuous  power   supply   to   the   pacemakers   which   is  discussed as follows.            The medical device which uses electrical  impulses that are delivered by the electrodes to  contract the heart muscles in order to regulate the  heart   beat   is   termed   as   pacemaker.   Its   main  purpose   is   to   maintain   adequate   heart   rate,  because the heart’s native pacemaker may not  be fast enough or there may be a block in the  heart’s   electrical   conduction   system.   A  pacemaker   is   generally   inserted   in   the   left  shoulder where an incision is made below the  collar bone creating a small pocket. Leads are fed  into the heart through large vein and the progress  of lead insertion is monitored using a fluoroscope.  The major drawback of pacemakers is that, they  use batteries which need to be replaced when
