The article shows the latest research outcome of new energy technologies in the marine ecological environmental sensor.

Harvesting water wave energy presents a significantly practical route to energy supply for selfpowered wireless sensing networks. They use a networked integrated triboelectric nanogenerator (NITENG) as a highly adaptive means of harvesting energy from interfacing interactions with various types of water waves. Having an arrayed networking structure, the NITENG can accommodate diverse water wave motions and generate stable electric output regardless of how random the water wave is. Nanoscaled surface morphology consisting of dense nanowire arrays is the key for obtaining high electric output.

This work proposes a viable solution for powering individual standalone nodes in a wireless sensor network. Potential applications include but are not limited to long-term environment monitoring, marine surveillance, and off-shore navigation.
