Ce qu'il fait
Most devices rely on outlets or bulky solar to recharge. This ultra-thin hybrid layer solves that by harvesting energy from motion, heat, and friction—enabling power in remote, mobile, or low-resource settings.
Votre source d'inspiration
Inspired by the global need for accessible energy, I wanted a solution that didn’t depend on sun, fuel, or plugs. The idea came while studying passive forces we interact with daily—motion, heat, and friction. I realized these could be harvested together in one compact, flexible layer. This design turns everyday use into usable power, offering a low-cost, off-grid charging solution for phones, wearables, and sensors—especially in places where energy access is limited or unreliable.
Comment ça marche
This design is a paper-thin energy-harvesting layer that passively generates electricity from motion, body heat, and friction. It combines three materials: a piezoelectric layer that makes power when bent or tapped (like during walking or typing), a thermoelectric layer that captures heat differences between your body and the air, and a triboelectric layer that produces energy from rubbing or contact (like holding or swiping a phone). These layers are stacked into a flexible sheet under 5mm thick. As you move or use your device, the sheet captures small bursts of energy, which are smoothed and stored in a capacitor or battery through a simple circuit. Over time, this builds up enough to charge a phone, wearable, or sensor—without any need for plugs, sunlight, or fuel. It’s fully passive, quiet, and designed to bring power to places where energy access is limited or unreliable.
Processus de conception
The idea began with a simple goal: to charge phones and small devices without plugs, sunlight, or manual effort. I explored how materials could produce electricity from everyday forces—like body heat, motion, and touch—and asked, what if we could combine them? I focused on three sources: piezoelectricity (from pressure or bending), thermoelectricity (from heat differences), and triboelectricity (from friction). I designed a layered structure using thin PVDF piezo films, a flexible thermoelectric mesh, and a triboelectric surface, all stacked under 5mm. These layers work together to generate energy from daily actions like walking, holding a phone, or body warmth. The outputs are routed through a simple circuit that stores the energy in a capacitor or battery. So far, I’ve developed technical diagrams, mockups, and a provisional patent draft. The system is designed for easy prototyping using off-the-shelf materials and could be integrated directly into phones or cases. While I haven’t built a physical prototype yet, the concept is refined and ready for testing or partnership. The next step is building a working unit to validate power output and efficiency.
En quoi est-il différent ?
What makes this design unique is its ability to passively harvest energy from three everyday sources—motion, body heat, and touch—using a single, ultra-thin, flexible layer. Unlike other devices that rely on solar panels, kinetic cranks, or single-source energy methods, this design combines piezoelectric, thermoelectric, and triboelectric materials in one stackable system under 5mm thick. It works without sunlight, movement triggers, or user input. There are no moving parts, and it’s small enough to fit inside a smartphone or wearable. It generates small amounts of power throughout the day, gradually storing energy without interrupting normal use. Most competing products only work under ideal conditions, while this system functions in pockets, at night, or while walking. Its low cost, constant trickle power, and adaptability make it a novel solution for off-grid charging, emergency use, or regions with limited electricity access.
Plans pour l'avenir
Next, I’ll refine the design for manufacturing and seek licensing or partnerships with companies in electronics or sustainability. I’m also exploring ways to deploy it in off-grid areas through NGOs. My goal is to make energy harvesting simple, affordable, and built into everyday tech—reducing reliance on chargers and expanding access to power where it’s needed most.
