Increasing Voltage In a Piezo Driven Circuit

Thread Starter


Joined Sep 16, 2015

First I would just like to say I am extremely new to circuits and electrical engineering in general. I have a very basic understanding and thats it although I am very eager to learn. With that being said I would like to introduce my problem. I have 4 Piezo Film elements wired together in series connected to a Bridge Diode or rectifier, whatever you want to call it. It produces very low voltage, around .3V-.4V and my problem is I want to use a boost converter to boost the voltage to 5.1V but the minimum input voltage for the boost converter is .7V. is there any way I can increase the voltage coming from the piezos to atleast .7V? I have read up on Joule thiefs and Voltage Mutiplier circuits but am unsure of their Viability. I am sorry if I have made any of this confusing and will answer any questions to the best of my ability. Thank you and I look forward to your responses

Attach your circuit, take the photo for the piezo and links the datasheet, before your upload the files, please compress the circuit as 800*600 *.gif, and the photos as *.jpg.
