Joint RF Energy Harvesting and Nanoelectronics for Self-Powered Water Leak Detection

Traditional water leak detectors rely on batteries, creating waste and requiring replacements. This research introduces a groundbreaking, self-powered system that eliminates batteries entirely. Our system uses a sensor with advanced nanomaterials that generate electricity when exposed to water. This electricity powers a Bluetooth chip to send real-time leak alerts. Uniquely, the system also harvests Radio Frequency (RF) waves from the environment, providing additional power to send daily "heartbeat pings" without relying on batteries. This innovative combination of fluid-responsive nanomaterials and ambient RF energy harvesting creates a self-powered, sustainable solution for water leak detection, offering long-term reliability and reduced costs.
