  10. 10. METHODOLOGY The working of footstep power generation system involves three distinct phases.  Sensor interface and Transducing:  Consists array of piezoelectric sensors Kinetic energy is converted into electrical energy Processing: Here the generated degraded vibrating voltage will be fed to different blocks of circuit element to get a proper output  Storage: Resultant output will be stored in a battery ECE Dept., Dr.MVSIT Footstep Power Generation System

  12. 12. WORKING  When ever pressure is applied on piezoelectric sensor that pressure is converted into Electrical energy  That minute voltage which is stored in the Lead Acid battery.  That voltage is used to drive DC loads.  Here we are using PIC16F778 to display the amount of battery get charged.

  15. 15. PIEZO ELECTRIC SENSOR •It is a device converts applied pressure into voltage by detecting the mechanical vibration • Here an array of 10 piezoelectric sensors are used for generation of power •The array will produce maximum 9v with 100mA current •lead zirconate titanate (PZT) and multilayer polyvinylidene fluo- ride (PVDF) are the 2 types of sensor in market •The voltage from the sensor array is fed to a filter 15 ECE Dept., Dr.MVSIT Footstep Power Generation System
  16. 16. FILTERING OPERATION •Generally a capacitor is used as filter to remove the AC content in the sensor output and to get pure DC •A capacitor is a storage device will store voltage for a minute time with charging and discharging phenomenon •It will acts as short circuit for AC and acts as open circuit for DC •The filter output is fed to unidirectional current controller 16 ECE Dept., Dr.MVSIT Footstep Power Generation System
  17. 17. UNIDIRECTIONAL CURRENT CONTROLLER •General examples for unidirectional current controllers are Diodes and Thyristors. •They will make the current flow in one direction by conducting to only one side •Here it is used to prevent the flow of current back to piezoelectric sensor •This voltage is then fed to the Battery for storing and Voltage divider circuit to provide reference voltage to LCD 17ECE Dept., Dr.MVSIT Footstep Power Generation System
