BUDDY EXPLAINER on Instagram: "In Japan, researchers are using smart pavements to turn everyday human movement into clean energy ⚡. These walkways are embedded with special piezoelectric materials that capture kinetic energy from footsteps. When people walk, run, or jump, the surface bends slightly, creating mechanical pressure. Piezoelectric crystals then convert this pressure into usable electricity 🔋. The generated energy can power street lights, public display screens, and even help track p
