ABSTRACT The growing demand for self‐powered wearable electronic devices in healthcare, fitness, and entertainment has driven significant advancements energy harvesting technologies. This review explores the latest progress mechanisms that enable sustainable autonomous devices, with a particular emphasis on role of polymers their development. Polymers offer unique combination mechanical flexibility, biocompatibility, lightweight properties, making them ideal applications. systematically categorizes major technologies into three primary mechanisms: thermoelectric generators (TEGs), piezoelectric harvesters (PEHs), triboelectric nanogenerators (TENGs). Each section provides an in‐depth discussion working principles, material innovations, fabrication techniques, applications these systems. Beyond fundamental mechanisms, discusses hybrid systems integrate multiple sources to maximize power generation ensure continuous device operation. storage technologies, such as flexible supercapacitors micro‐batteries, is also highlighted address intermittency challenges ambient sources. Despite progress, remain improving conversion efficiency, enhancing durability, optimizing system integration real‐world identifies key research directions overcoming challenges, including advanced materials engineering, miniaturization artificial intelligence‐driven management strategies. findings presented this provide valuable insights development next‐generation paving way efficient electronics seamlessly daily life.
