  1. 1. Foot Energy Generation Application of Piezoelectric Effect
  2. 2. Vishwakarma Government Engineering College Chavda Rajesh D. Dabhi Nirav R. Ghediya Jagir P. Kalsariya Rohit R. Suratwala Neel U. 150170119007 150170119008 150170119015 150170119019 150170119057
  3. 3. Founder of Piezoelectric Effect • Pierre Curie & Jacques Curie – two curie brother discovered the PIEZOELECTRIC EFFECT in 1880.
  4. 4. Piezoelectric Effect The generation of an electric charge in certain non- conducting materials , such as quartz crystals & ceramics , when they are subjected to mechanical stress such as pressure or vibration is known as PIEZOELECTRIC EFFECT.
  5. 5. Piezoelectric Circuit
  6. 6. Piezoelectricity is the electric charge that accumulates in certain solid materials such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure. It is derived from the Greek piezo or piezein , which means to squeeze or press, and electric or electron , which means amber, an ancient source of electric charge. The piezoelectric effect is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials with no inversion symmetry. The piezoelectric effect is a reversible process in that materials exhibiting the direct piezoelectric effect also exhibit the reverse piezoelectric effect. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.1% of the original dimension. Conversely, those same crystals will change about 0.1% of their static dimension when an external electric field is applied to the material. The inverse piezoelectric effect is used in production of ultrasonic sound waves.
  7. 7. Application of Piezoelectric Effect • High Voltages & Power Sources • Sensors • Foot Step Energy Generators • Actuators • Frequency Standard • Piezoelectric Motors • Reduction of Vibration & Noise • Infertility Treatment • Surgery • Potential Application
  8. 8. Foot Step Energy Generation • Today World is going through shortage of sources of energy so we have to think about this worldwide problem. Piezoelectric effect helps us in producing our mechanical energy or mechanical pressure into electricity. • Foot step energy is one of application of piezoelectric effect which can be used in two different ways: I. Installing piezoelectric sensors in Pathways - Footstep energy Harvesting II. Installing Piezoelectric sensors in Shoes - Footstep energy Generation
  9. 9. Foot-Step Energy Harvesting Generating electrical power as non-conventional method by simple walking or running on the foot-step. Non-conventional energy using foot- step is converting mechanical energy into electrical energy.

  11. 11. Working When ever force is applied on piezo electric crystals that force is converted to Electrical energy is used to drive DC loads. And that minute voltage Which is stored in the Lead Acid battery. The battery is connected to the inverter.  This inverter is used to convert the 12 Volt D.C to the 230 Volt A.C. This 230 Volt A.C voltage is used to activate the loads. We are using conventional battery charging unit also for giving supply to the circuitry.
  12. 12. •An area of France named Saint Omer has installed the technology which is called FOOTSTEP ENERGY HARVESTING. •The technology is invented by PAVEGEN TECHNOLOGY.
  13. 13. Advantages Reliable, Economical, Eco-Friendly. Less consumption of Non- renewable energies. Extremely wide dynamic range, almost free of noise - suitable for shock measurement as well as for almost imperceptible vibration  Excellent linearity over their dynamic range Compact yet highly sensitive  No moving parts - long service life  Self-generating - no external power required  Great variety of models available for nearly any purpose
  14. 14. Main Era of Foot-Step Harvesting The project “FOOT STEP POWER GENERATION FOR RURAL ENERGY APPLICATION TO RUN A.C. AND D.C. LOADS” is successfully tested and implemented which is the best economical, affordable energy solution to common people. This can be used for many applications in rural areas where power availability is less or totally absence. As India is a developing country where energy management is a big challenge for huge population. By using this project we can drive both a.c. as well as D.C loads according to the force we applied on the piezo electric sensor.
