Is it possible to convert heat to electricity using Peltier Module?
 
I need to know because i need a chip that is a conductor and absorbs heat then converts it to electricity.

Welcome to PF!

Yes - and it is done - but not very efficiently. http://en.wikipedia.org/wiki/Automot...tric_generator

if you have a gas powered appliance in your home you have suh a device. it's the "thermopile" that is in the pilot lihjy flame. it makes a small amount of power to hold the gas valve open vial a small electromagnet, and if pilot light goes out the gas supply is shut off.

you can get one from a hardware store or a discarded water heater to tinker with.
i dont remember the voltage they make but i doubt it's more than two volts.

Thank you for the response!

I was looking for the chip that can absorb waste heat from any conductors then convert it to electricity... I'm not very sure if it's the peltier module.

Your looking for a thermopile.

A thermopile looks kind of like a peltier plate. It's composed of an array of thermocouples that output electricity when they are exposed to heat.
