An extremely low temperature environment operatable hybrid dual-functioning energy device driven by a supercapacitor/piezo–triboelectric generator system
Abstract:Maintaining the quick-charging capacity of flexible supercapacitors (SCs) at low temperatures is a significant challenge. At reduced energy levels, the charging performance of piezo-triboelectric nanogenerators (PTNGs) using composite electrodes often...
The vigorous development of wearable and implantable electronics provides a series of new solutions for human health monitoring and disease diagnosis and treatment. Considering the particularity of the operating environment, this also puts forward higher requirements for energy storage devices (ESDs). Supercapacitors stand out from many ESDs due to their unique advantages, such as high power density, long life, and ease of fabrication. For different application requirements, supercapacitors are developing toward flexibility, multifunction, and integration. This review highlights the recent progress in developing supercapacitor‐integrated systems. Smart supercapacitors with unique properties, their applications, and integrations with various sensors and/or energy‐harvesting devices are discussed and summarized thoroughly. Furthermore, the all‐in‐one device enabled by compatible materials and ingenious structure design is also described. From practical perspectives, the key challenges facing the development of supercapacitor‐integrated systems are presented, and the suggestions for future research directions are given.
