  That's a great idea.But I think the power generation will be unstable as number of people walking on that sheet will vary,won't it?

  narayana murthy

  @ishu: no ishu i think it may be like using animals do you seen in any movies or any shows
  a rabbit is running on a rotating wheel and we generate electricity
  like wise here humans walk on sheet and some electricity can be generated there may be some problem as you ask but thats not a main problem here as we in this century
  
  @vik: i think i never heard about that sheet if your sure i am with you to help in anyway
  try for it i am supporting you
  
  as it is eco-friendly 👍
• 

  ISHAN TOPRE

  @NM:yeah I agree with you that it is ecofriendly but what we need is a reliable source of energy.For example there may be hours when nobody walks on that sheet so power cannot be generated ,can it be?
• 

  narayana murthy

  @ishu: you may be right so we install it in various places and takes energy
  the main role in electricity takes place is how we generated it and how much efficiently we use it
  so in my view we place it in heavy traffic places like where traffic is there at the mid night too
• 

  ISHAN TOPRE

  Ok,Then let it not be a lone source of power.It can be supplemented by conventional sources.
  For example a signal can be run normally with electricity but can be supplemented for by this PVDF sheet.Something like a generator or invertor.😀
• 

  narayana murthy

  Sorry ishu i cant understand what your saying
• 

  ISHAN TOPRE

  You know mixed petrol? In it we mix ethanol+petrol,right?
  Similarly we can reduce load on conventional electricity by supplementing it with PVDF power.
  
  one more suggestion:Constructing road of PVDF sheet may be little more costly why don't we just use this technology in speed breaker(Imagine an assembly with asomething like a spring below it which somehow generates powerif applied load)? Whenever a vehicle will pass over that speed breaker,It will compress the spring below it thus generating power.
• 

  narayana murthy

  May be your right ishu but there is a problem if we keep it in below speed breaker all vehicles go slowly so,much electricity cant be generated then coming to cost i agree with you a bit costlier so why cant we make the sheet with less cost material
• 

  vikeshrajan

  Hi frnds,We r replacing PVDF sheet by PZT,bcoz its cost is little bit low.
  It generate more power compared to PVDF

  I remember seeing this in a documentary about new technology on Discovery. What they did was put piezoelectric material in the footpath. So when people walked, they produced some electricity. This was used to charge nearby batteries and run the street lights, traffic lights, parking meters etc. It was in a shopping complex. And it has been a while since this prokect was started and it is working fine.
  Will try and give you a link about it. Will have to search it first. And if I remember correctly, I think it was in Sweden.

  As I said I am not sure whether it was Sweden but I know that it was a European country. They had used the same concept of using a piezoelectric material to generate electricity for use in a local plaza of some kind. The material was fitted in footpaths and as the people walked on it, the resulting stress produced electricity.

  Hi frnds,
  I done my project 'Power generation through footsteps' on MATLAB package,there runtime is very slow almost 2hrs..So we r plan to do it in another package........help us....did any one know software package thoroughly means ,send hou to use..............😒
• 

  narayana murthy

  how about pspice

  Not exactly powered by footsteps, but they claim 30kw/hr from normal vehicle traffic...not too shabby!
• 

  vikeshrajan

  @narayana murthy:Ya ,I tried in Pspice but I did not get the result even for first stage..........I tried 2 times,I got a same error............The error faced r
  
  1.less than 2 connections at node N00782
  2.Less than 2 connections at node N00814
  3.Node Noo782 is floating
  4.Node N00814 is floating
  
  
  
  I will send my first stage ckt.....
• 

  vikeshrajan

  @narayana murthy:I dont know how to copy the ckt diagram........
  
  The capacitor is in series with voltage source and two reistors
• 

  narayana murthy

  @vikesh: i think it is better to write the program relavent to circuit diagram
• 

  vikeshrajan

  @narayan:how?
• 

  vikeshrajan

  Hi frnds,the output of Piezoelectric material is ac r dc..
• 

  narayana murthy

  program coding like did you seen any pspice books
  they gives codes for every sources like
  source node1 node2 value
  such a coding i dont know exactly how to say
  refer to books for additional data about coding
• 

  vikeshrajan

  The output of piezocrysal is ac........positive going wave is due to compression and negative is due to tensile
• 

  vikeshrajan

  can anybody tell how to boost up the power in a circuit(if the input is dc)............

  magelec

  hi ,
  what if we can use hydraulics under the speed breaker
  we install a simple system and use an under ground turbine
  it may be more reliable
  what is your opinion
• 

  magster

  maglec that is a good option but the point is where will you put the turbine and how?
• 

  narayana murthy

  magster

  maglec that is a good option but the point is where will you put the turbine and how?

  i think it can done by making a turbine underground we take a place and we keep a turbine at low level i think this is what he is saying
  
  @maglac: it may be nice but i think its difficult and kinda costly
• 

  PraveenKumar Purushothaman

  But are you saying you can place a turbine under a speed breaker???
• 

  praba230890

  You can never have such a doubt.....as u know piezoelectric principle when a variable pressure is applied to a piezoelectric material it produces voltage which depends on the amount of pressure applied.The amt of pressure applied is variable as we know so for sure voltage developed is variable which is then A.C.
• 

  praba230890

  First of all guys be clear in this thing that we are going to fit the piezo resonator in footwear or in the road, then start design a system. If you want to charge up your mobile phone or any battery while you jogging or walkin i,e personal use you better fit it in footwear and while you want to get a huge power then surely roads.
  
  Already most of the sensors in railway crossovers which indicate the train's arrival uses piezo resonators to obtain power. I've already done a project on this piezoelectric power generation and i did it for charging up industrial sensor's . If any one wants to over go through my project better ask me i'll send u my report.(Green it......)

  PraveenKumar Purushothaman

  That's great... So, what have you decided till now... I mean, the plan?
• 

  magelec

  narayana murthy

  it may be nice but i think its difficult and kinda costly

  what i am sayingis that when a car passes over the speed breaker
  ithe hydraulic piston wil put pressure on the liquid which can then be used to turn a turbine
  this wont cost much

  hahaha nice joke is turbine is coming for you at the cost of free to place in underground
  its too difficult at initial and maintainance cost

  what is funny in that
  it is a full proof system
  and also
  what are taxes for huh

  sorry for late reply i am saying about cost if it is not payable no one will encourage for it and think if any problem occour in turbine repair is too hard
• 

  vodin

  So the voltage has to be regulated as it will be highly variable. What about the circuitry needed for that? and besides, if it is to be stored in batteries dc conversion is needed. How will the need for all this affect the overall efficiency? im talking about cost vs output.

  yeah ... i just now about the principle only , so please tell me about working procedure briefly . As am a student , i would like to make a working model ... so , help me to make it ..
• 

  narayana murthy

  principle is simple piezo electric crystals are meterials which convert mechanical energy intlo electrical energy.
  That means how much stress you produce on them that much energy will be generated.
  And limits will be depended on crystal quality

  okey .. Narayana murthy ,but , i wanna know about construction view .. cuz i wanna show in practically.. howi can i make a working model

  Guys you have a great topic.but is efficiency is less but as the @#-Link-Snipped-# says if we can assemble more tricks then we may be able to run this idea.for eg. everybody knows about solar energy but it is not at night,you guys talks about pizoelectric transformer but it has less efficiency,we can use solar panels on walls which uses the bulb emitted light again etc.now the benifeats are i think a solar pannel has life about 8-10 years and we should paint walls approx. 2 times a year then the coast may be settled or not.the solar energy can't be at night but if we store it in dc form then can be used at night and the footprints energy also can be stored.so
