Nanogenerators are energy-harvesting devices that create electricity from waste mechanical energy in the environment.Triboelectric layers are made of a variety of materials, including polymers, metals, and inorganic compounds.
The most widely utilised materials are dielectric polymers such as PTFE, FEP, PDMS, and Kapton.An electric generator, commonly known as a dynamo, is any machine that converts mechanical energy into electricity for transmission and distribution to residential, commercial, and industrial consumers via power lines.
Generators also provide the electrical power required by autos, aircraft, ships, and trains.
The Global nanoscale power generator market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The nanogenerator developed by PNNL captures ocean energy to power sensors and other devices, with larger versions of the generator intended to power ocean observation and communications systems such as acoustic and satellite telemetry.
A PNNL laboratory fellow and co-developer of the new TENG device, along with their team, have created a patent-pending frequency-multiplied cylindrical triboelectric nanogenerator (FMC-TENG), which uses carefully placed magnets to convert energy more efficiently than other cylindrical TENGs and better transform slow, uniform waves into electricity.
TENGs are low-cost, lightweight devices that can efficiently convert slow, uniform, or random waves into power, making them ideal for powering devices on the open ocean where monitoring and access are difficult and expensive.
So far, the FMC-TENG prototype has been able to generate enough electricity to operate an acoustic transmitter – a sort of sensor commonly seen on ocean monitoring platforms that can be used for communications.
This is roughly the amount of electricity required to power an LED light bulb. They were working on the FMC-TENG to power anything from ocean observing platforms with many sensors to satellite communications, all using ocean power.
The more energy a cylindrical TENG creates, the faster it moves. As a result, quick, frequent waves can generate more energy than slower, more uniform open ocean waves.
Deng and his team set out to enhance the quantity of wave energy turned into electricity in the FMC-TENG in order to create a TENG that could power devices on the open ocean. According to PNNL, the trick was to temporarily halt the FMC-TENG’s inner cylinder from moving.
