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.

Triboelectric nanogenerators (TENGs) have quickly become one of the most popular mechanisms for harvesting ambient mechanical energy due to their simple design, facile construction, abundance of material choices, and cost‐effectiveness. Over the past decade, TENG research has been heavily focused on methods of construction that improve output or function in specific applications. Recently many researchers have looked to the design of the world around them to create more advanced TENGs, investigating the unique qualities that organisms use to survive and thrive in their environments. These bioinspired TENGs are often more efficient, more environmentally friendly, or possess more capabilities than their standard TENG counterparts. Herein, this paper provides a review of recent advances in TENGs that utilize inspiration or novel materials from nature for use in biomonitoring, artificial intelligence texture detection, wind energy harvesting, blue energy harvesting and other applications. The unique qualities of these TENGs include sweat‐resistance, biodegradability, increased output parameters, and more. This review is organized into plant‐inspired, animal‐inspired, human‐inspired, and other bioinspired TENGs. Each study's source of inspiration, the problems they sought to address, and the output parameters of the device are discussed, followed by a discussion of current challenges and promising future directions for field advancement.

The flexible self-powered display system integrating a flexible triboelectric nanogenerator (TENG) and flexible alternating current electroluminescence (ACEL) has attracted increasing attention for its promising potential in human–machine interaction applications. In this work, a performance-enhanced MXene/cellulose nanofibril (CNF)/MXene-based TENG (MCM-TENG) is reported for powering a flexible patterned ACEL device in order to realize self-powered display. The MCM multilayer composite film was self-assembled through the layer-by-layer method. The MCM film concurrently acted as a triboelectric layer and electrode layer due to its high conductivity and strength. Moreover, the effect of CNF concentration and number of layers on the output performance of TENG was investigated. It was found that the MCM-TENG realized the optimum output performance. Finally, a flexible self-powered display device was realized by integrating the flexible TENG and ACEL. The MCM-TENG with an output voltage of ≈90 V at a frequency of 2 Hz was found to be efficient enough to power the ACEL device. Therefore, the as-fabricated flexible TENG demonstrates a promising potential in terms of self-powered displays and human–machine interaction.
