VIBRATIONAL ENERGY HARVESTING POWER FROM ROAD SPEED BRAKER

  1. 1. V.SATHISH VELAMMAL INSTITUTE OF TECHNOLOGY CHENNAI
  2. 2. INTRODUCTION  Energy harvesting sources including solar, wind and thermal each with a different optimal size. They either waste much available energy due to impedance mismatch, or they require active digital control that incurs overhead, or they work with only one specific type of source. No more research on the vibration domain
  3. 3. PROPOSED SYSTEM  This paper has investigated the optimal power that can be extracted from ROAD SPEED BRAKER over a wide speed range using electromechanical vibration conversion from human movement. Driven by the potential to power small portable electronic devices, more recent research in energy harvesting from ROAD SPEED BRAKER has focused on 1) increasing the power output 2) energy harvesting from the motion of vehicles.

  5. 5. OPERATION
  6. 6. EXPLAINATION  mechanical stability of the piezoelectric transducer under large mechanical stress  Piezoelectric transducer plate is kept at the bottom of the speed breaker, so when the vehicle passes through speed breaker on the spot it compresses and produces pressure which is then used to produce electricity.
  7. 7. APPLICATIONS  Long lasting operability  No chemical disposal  Cost saving  Maintenance free  No charging points  Inaccessible sites operability  Flexibility  Applications otherwise impossible
