Researchers at ETH Zurich developed an automated system called GrimACE to detect pain in laboratory mice [1]. The technology uses infrared cameras and artificial intelligence to monitor subtle changes in facial expressions [2]. By tracking orbital tightening and whisker positions, the system provides a more objective measure than manual human observation [1][3].
The AI-driven approach aims to improve animal welfare and ensure consistency across scientific studies [1]. GrimACE allows for continuous monitoring without human interference, reducing stress for the animals involved [3]. This innovation represents a significant shift toward more humane laboratory environments for research [2].
