Transient, Biodegradable Energy Systems as a Promising Power Solution for Ecofriendly and Implantable Electronics

Abstract

Along with the rapid growth in electronics technology, electrical power solutions are developed to provide high‐performance, reliable, and durable energy supplies to various electronic devices. However, conventional power systems are challenging owing to serious after‐use considerations, including environmental costs and biological hazards of eliminating heavy metals and other toxins. Here, this Perspective provides a comprehensive review of recent progress in techniques associated with transient, biodegradable, environment‐friendly energy solutions, including batteries, supercapacitors, energy harvesters utilizing various types of energy sources (e.g., biochemical, physical/mechanical, or thermal), and external energy transfer strategies (e.g., inductive coupling/radiofrequency, photovoltaic, or ultrasonic). Key features, practical examples, existing challenges, and finally possible future directions for transient, biodegradable energy solutions with unmet approaches yet are presented.
