Recent advances in wearable self-powered energy systems based on flexible energy storage devices integrated with flexible solar cells

Abstract

Wearable electronics are considered to be an important technology in the next-generation smart electronics. Meanwhile, the ever-increasing energy consumption and the growing environmental awareness have highlighted the requirements of green and renewable energy. Integrating flexible photovoltaic cells (PVCs) with flexible energy storage devices (ESDs) to construct self-sustaining energy systems not only provides a promising strategy to address the energy and environmental issues, but also enables the entire system to be operated continuously without external charging, which is considered to be a promising direction for future wearable electronics. Herein, we summarize the recent progress in the wearable self-sustaining energy systems based on the flexible ESDs integrated with flexible PVCs. First, the recent development in the flexible PVCs and their characteristics are summarized. Following that, we discuss the advances of the flexible ESDs used in the wearable electronics. Then, we give a short discussion on the integration of flexible ESDs with flexible PVCs. Thereafter, various functional applications of these self-sustaining energy systems in wearable electronics are introduced. Last, the main challenges and future perspectives of self-powered energy systems for wearable electronics are discussed.
