A simple, but very powerful idea. Angelo Casimiro, fifteen -year -old maker passionate about sustainable technology, has created a generator of electric current hidden in the shoes. The principle is that of piezoelectricity: Each step produces a small amount of energy, which is collected, regulated and stored. The result? After eight hours of continuous runninghe managed to completely recharge a 400 mAh lithium ion battery.
That’s not all: after one two -hour basketball matchthe same technology has managed to generate enough energy from load a powerbankeven if with a slightly lower output voltage. In a short video shared online, Angelo shows the device in operation: his shoes, while moving, become real portable micro-generators.
All the materials and steps explained on Instructables
If the idea fascinates you and you want to try to make it home, Angelo has published one Detailed guide on Instructables. The project is designed to be accessible also to those with basic electronic skills. Here’s what you need to start:
The heart of the system are the Piezoelectric transducerscapable of generating energy from the pressure exerted by your steps. These electrical signals, still raw, come rectified and stabilized From the diodes, then transferred to Powerbank through simple electrical connections. Everything can be installed inside the shoes sole, with the help of resistant sticker or insulating tape.
An intelligent, sustainable and replicable idea, perfect for those who love to walk and want produce clean energy simply by moving.
Angelo’s shoe is only one of the most creative examples of how we can transform our daily movement into renewable energy. Another interesting project is Solepowera system that uses the walk to power electronic devices. The mechanism recalls that of a crank torch: each step runs a micro-generator that produces current.
But scientific research is going further. Some engineers are studying the Reverse ElectroWettinga technology that uses liquid metal microgocce present in the soles. The movement of the foot causes the flow of drops, which in turn generate a small but constant flow of electric current.
We are only at the beginning of a revolution that could transform each walk into a clean energy sourcedecentralized and accessible to everyone.
