A new cylindrical triboelectric nanogenerator (TENG) is a small powerhouse that converts wave energy into electricity to power devices at sea.
Researchers at the US’ Pacific Northwest National Laboratory are working on the development of a new cylindrical triboelectric nanogenerator —a small powerhouse that converts wave energy into electricity to power devices at sea.
“TENGs are low cost, lightweight, and can efficiently convert slow, uniform or random waves into power—making them particularly well-suited to powering devices in the open ocean where monitoring and access are challenging and costly,” said Daniel Deng, a PNNL laboratory fellow and co-developer of theDeng and his team took a novel approach to advance cylindrical TENGs for use on the open ocean.
“We’re developing the FMC-TENG to power everything from ocean observing platforms with multiple sensors to satellite communications, all using the power of the ocean,” Deng said.The triboelectric effect – the same effect researchers leverage in the FMC-TENG to produce power – is similar to what people experience when shocked by static electricity. A cylindrical TENG is made up of two nested cylinders with the inner cylinder rotating freely.
The more a cylindrical TENG moves, the more energy it generates. That’s why fast, frequent waves can generate more energy than the slower, more uniform waves of the open ocean.
