New physics-informed framework enables real-time fall detection on edge devices

Researchers have developed a novel physics-informed framework for real-time fall detection on low-power edge devices. This approach models falling as a loss of stability in a coupled dynamical system, utilizing a dual-Liquid Time-Constant (LTC) neural network architecture. The system continuously models inertial trajectory evolution and ground-contact adjustments, with a coupling module emulating physical interaction. A Stability Manifold classifier then detects boundary crossings using Lyapunov-inspired metrics, enabling irreversibility assessment and early warning. AI
