i am working on piezoelectrics sensors.now after converting the voltage from ac to dc i need to store it in a btttery so that i can further use it as any charging device (THATS later part).Now i need an idea ,that the voltage through these plates is discontinuous,my ques is that is there any problem in charging a battery with discontinuous voltage ,if no then its ok ,but if there is a problem ,what can i do to make voltage continuous, or any suggestion u guys have .

thankyou

You can use some kind of energy harvesting circuit. For example this one.
