Pressure Plate Energy Harvesting System
A concept for sustainable, footstep-powered energy collection
This system captures kinetic energy from footsteps using a thin, modular pressure plate design. Inspired by energy-harvesting infrastructure in high-traffic environments, the goal is to convert everyday human movement into usable electrical energy for low-power devices such as sensors, lighting, or indicators.
Overview
Problem
Future Plans
High-traffic public spaces generate significant mechanical energy that is typically wasted. The challenge was to design a system that could efficiently capture this energy without altering user experience, while maintaining a compact, low-profile, and durable structure suitable for real-world integration.
