(Phys.org) —As sources of renewable energy, sun and wind have one major disadvantage: it isn't always sunny or windy. Waves in the ocean, on the other hand, are never still. American researchers are now aiming to use waves to produce energy by making use of contact electrification between a patterned plastic nanoarray and water. In the journal Angewandte Chemie, they have introduced an inexpensive and simple prototype of a triboelectric nanogenerator that could be used to produce energy and as a chemical or temperature sensor.
Do you think this technology could be applicable soon?

Water-Solid Surface Contact Electrification and its Use for Harvesting Liquid Wave Energy
in this work: A newly designed triboelectric nanogenerator is based on the contact electrification between a patterned polydimethylsiloxane pyramid array and water. Cost-effective and simple, the prototype triboelectric nanogenerator shows the potential to harvest energy from liquid waves and serve as chemical and temperature sensors.
