    design a circuit that can store electric

    i currently doing my FYP, i want to design a circuit that can store electric that total amount of electric is a few milivolt.

    i need sample circuit, that i generated the electric by using transducer, and then i store the electric after transducer, this circuit must confirm that no electric return back to the transducer. the store energy circuit maybe will then used to recharge battery.

    but i just stuck, i don't know how to start, i don't know how to design a circuit, i need your help to provide me the a sample circuitry that can store the energy. or show me the e-book that related. provide the link please

    your help will be deeply appreciate!

    How many coulombs? What's wrong with a high quality capacitor?

    dear john, thanks for reply

    i don't know how many coulomb will be generated , i will using piezoelectric transducer to generated electric. can you provide me some sample circuit.

    You can follow the transducer with an appropriate amplifier and use some type of RC circuit or peak detector on the amp output to quantify the signal. This is a rough idea, but it lets you use the transducer.
