This week I'm exploring the world of energy harvesting based on a recent stay at a friend's house where they had switches without wires and batteries.
Their setup used switches that did not use any power source, instead they use some of the mechanical energy that you input by pressing the switch to generate a small amount of electricity and send a signal to a receiver, indicating that the switch is pressed.
I additionally explore how we can generate some electricity with a piezo element as well as go into details of making a peltier based thermoelectric generator that even generates enough energy to spin a DC motor for quite some time.
These examples can be used to power some device that can then send data to a receiver and we can act upon it to trigger certain appliances or events.
