The utilization of sensors has become indispensable in the advent of an intelligent era characterized by artificial intelligence, 5G communication, big data, and other cutting-edge technologies. Traditional sensors require external power sources or batteries, resulting in a complex sensing system that does not promote the development of sustainable and environmentally friendly applications for health monitoring. In recent years, the electrical output and stability of piezoelectric, triboelectric, thermoelectric, and hybrid nanogenerators have been significantly improved, enabling their widespread role in the development of self-powered sensors. The sensors are capable of performing sensing tasks by converting their own energy, thereby obviating the need for an external power supply. In this paper, we initially explore the operating mechanisms, device materials, and structures of diverse nanogenerators and evaluate their output efficacy. Subsequently, we showcase the latest advancements in self-powered sensor systems, spanning various fields such as biomedical and healthcare, wearable devices, sound monitoring, smart vehicles, environmental monitoring, and smart cities. The paper also explores the future potential of self-powered sensor systems, in addition to discussing their practical applications.

Flexible thermoelectric generators (FTEGs) represent an excellent solution for energizing wearable electronics, capitalizing on their ability to transform body heat into electrical energy. Nevertheless, their use in the wearable industry is limited by the insufficient thermoelectric (TE) efficiency of materials and the minimal temperature variation among the devices. In this study, we have developed a Lego‐like reconfigurable FTEG by combining flexible TE chips, rheological liquid‐metal electrical wiring, and a stretchable substrate in a mechanical plug‐in configuration. The flexible TE chips are constructed from n‐type all‐inorganic MXene/Bi2Te3 composite films, which have their TE properties further enhanced through heat treatment. A demonstration of the FTEG illustrates its capability to convert heat into vertical temperature difference (ΔT), leading to a substantial ΔT at the cold end in contact with the environment, resulting in a power output of 7.1 μW with a ΔT of 45 K from only 5 TE chips. The reconfigurable FTEG presents significant potential for wearable devices to harness low‐grade heat.
