Self-Powered Livestock Ear Tag Uses Kinetic Energy and Machine Learning for Health Monitoring

Researchers have developed a self-powered ear tag that utilizes machine learning to monitor livestock behavior and welfare. The device converts the animal’s natural movement into electrical energy to power its sensors, eliminating the need for external batteries while tracking health indicators in real time.

The ear tag integrates a triboelectric nanogenerator, which captures kinetic energy from the animal’s head movements to maintain a continuous power supply. Onboard sensors collect data on activity levels, feeding patterns, and potential signs of illness or distress. A machine learning algorithm processes this data to identify behavioral changes, allowing farmers to receive automated alerts regarding the status of individual animals. By removing the requirement for battery replacements, the technology offers a sustainable method for long-term health monitoring in large-scale agricultural environments.
