Hi all.
My group is doing a project that is basically trying to harvest noise and convert it to electrical output. We actually have designed a tube to amplify the sound, and at the end of the tube we will put a piezoelectric material to convert the received sound to electrical output. We want at least our device will lit on a common LED.Well, more deflection to piezoelectric material means more energy output but noise doesnt provide much deflection to the piezoelectric.
We already measured the voltage output from the piezo and we only acquired around 30mV which is very small. The LED to be used would require at least 1.5V, but now we only have 30mV. So, we got to design a circuit which is capable of increase the voltage to at least 2V and send it to the LED.Since we have very low power voltage, how can we increase the voltage? What kind of electrical component that can be used to increase it? Is there anyway to increase it to 2V so that can be used to lit on 1.5V LED?
I really need your help.Any suggestion is appreciated.
