Triboelectric nanogenerators have recently gained enormous attention as a low‐cost method for converting abundant mechanical energy into electricity. Here, a continuous direct current (DC) output from a triboelectric nanogenerator (TENG) is achieved using two dimensional (2D)‐WS2/Si heterojunctions, without any need for a rectifier circuit element. At the interface of the p–Si and n–WS2 heterojunction, the “Tribo‐photovoltaic effect” is observed, responsible for the generation of direct tribo‐outputs. The demonstrated multifunctional DC‐TENG with remarkable performance can concurrently convert mechanical and photonic energy into an electrical one. In comparison to dark conditions, the device's output performance is enhanced under UV illumination (365 nm, 1022 µW cm−2), and the exhibited output voltage (10.75 V) and current (466 nA) are higher by a factor of 3.9 and 2.4, with excellent power harvesting ability and outstanding robustness. This versatile DC‐TENG is demonstrated to be an attractive platform for high‐performance vision sensors and UV detection, which has significant implications for the rapid development of self‐powered portable sensing and IoT devices based on Si CMOS technology.

Sensors play a crucial role in enhancing the quality of life, ensuring safety, and facilitating technological advancements. Over the past decade, 2D layered materials have been added as new sensing element in addition to existing materials such as metal oxides, semiconductors, metals, and polymers. 2D Layered materials are typically characterized by their single or few‐layer thickness and offer a high surface‐to‐volume ratio, exceptional mechanical strength, and unique electronic attributes. These properties make them ideal candidates for a variety of sensing applications. This review article focused on utilizing 2D layered materials in triboelectric nanogenerators (TENGs) for different sensing applications. The best part of TENG‐based sensing is that it is self‐powered, so no external power supply is required. The initial part of the review focused on the importance of the 2D layered materials and their innovative integration methods in TENGs. Further, this review discusses various sensing applications, including humidity, touch, force, temperature, and gas sensing, highlighting the impact of 2D layered materials in enhancing the sensitivity and selectivity of TENG sensors. The last part of the review discusses the challenges and prospects of TENG‐based self‐powered sensors.
