1. Thermoelectric USB charger
Today we are going to generate electricity from the difference in the heat it's nothing but Seebeck effect. We have to select the optimum material which is having high Seebeck coefficient. If we put in series also its mard even to generate 10mV. Peltier materials.
2. Electric Field detector
Most people who work with basic electronics would tell you that the worst part about it is getting small electric shocks! So what do we do to prevent this? But working with electrical components isn't the only time you get shocks. You can also get small shocks when you walk on a dry carpet, or even when you touch a doorknob sometimes.
