Water is abundantly present on Earth. Water waves have the unique feature of being random and irregular. The impact of water waves can be utilized to derive power by employing a triboelectric nanogenerator (TENG). Fishing is one of the main occupations in our society, and fishermen risk their lives every day for their occupation. During fishing, they face many obstacles such as heavy wind, fog, and tides, and these scenarios force them to lose their fishing nets in the sea. The loss of fishing nets not only leads to financial damage to the poor fishermen but also adds plastic pollution to the water bodies. A low cost, user-friendly approach to finding their fishing nets is highly desirable. Here, a self-powered smart fishing net-tracking buoy is developed for identifying fishing nets via integration of a Smart Buoy-Triboelectric Nanogenerator (SB-TENG), a power management unit, Arduino, and a Bluetooth controller using a smartphone. By scavenging blue energy, the SB-TENG device generates an open-circuit voltage of 900 V, and a short-circuit current of 11 μA and integration of multiple units of SB-TENG further enhances the performance. The SB-TENG was studied and demonstrated as a feasible power source that can commute instantaneous remote switching operation of LEDs. Moreover, by combining SB-TENG with Arduino and the Bluetooth controller, it acts as a self-powered wireless control system. This work demonstrates an effective method for scavenging blue energy and its potential application as a user-friendly, cost-effective, and self-powered smart fishing net tracking buoy.
