    I am a student of ME. I am doing my final year project on
    piezoelectric in shoes. Piezoelectric is located in shoes, while
    walking, piezoelectric compressed and it generates an electric
    this electric signal is stored in capacitor in other words, this
    electric signal charges a capacitor.

    I need a piezoelectri for this application. which type of electric
    suits? which specifications i need to buy it? do you have any idea ,
    from where i can buy it online?

    I recommend you review this article and make your own "organic"
    transducers using Rochelle Salt.

    Good luck! Keep us posted!

  3. I need a piezoelectri for this application. which type of electric
    There are Buzzers for a few ct around. I use them as lowcost force sensors
    and cheap vibration detectors :)
    Other lowcost piezos are found in one way cigarette lighters (is this right

    But remember: with piezo you will be able to get much voltage but not much

  4. If you want to generate POWER it might be better to make a capacitor with a
    compressible insulator - silicone rubber f.ex. & graphite rubber for
    electrodes - and keep a suitable bias voltage on it. When the capacitor is
    compressed, it's capacitance will increase and it will "suck" charge from
    the bias source. When the compression is released, the capacitance decreases
    and the voltage increases due to energy conservation i.e. power is

    I = C * dv/dt
