High‐Entropy Energy for Self‐Powered Systems

SmartSys, Volume 1, Issue 2, June 2025.
ABSTRACT In energy constrained application scenarios, self‐powered systems (SPSs) are gradually emerging as a core technological pathway for enabling distributed intelligent sensing. High‐entropy energy, such as micro‐wind, vibrations, water motion, and human activity, is widely available but difficult to harness due to its low density, randomness, and
