Cellulose-based droplet triboelectric nanogenerator coated with slippery omniphobic covalently attached liquid

With the revolutionary development of society, artificial intelligence, big data and cloud computing are greatly changing our life.

An abundance of mobile and smart devices like detectors, sensors or other intelligent instruments that requiring energy.

However, conventional centralized energy supplier system such as grid cannot meet the great demand of these devices and may be costly due to implement of electricity lines or frequently batteries replacement. A new energy supply method is wanted for satisfying the huge demand. Meanwhile, the widespread droplet energy is ignored that saves huge energy from solar and gravity.

By combination with triboelectric nanogenerator, droplet can fulfill the energy requirements for remote and smart devices.

The droplet based triboelectric nanogenerator is different from other wind/solar based energy system which is ineffective on windless and rainy day. It provides a new strategy to remote electricity supplier.

In order to improve the performance of droplet based triboelectric nanogenerator and decrease the negative effect to environment, we are proposed to use slippery omniphobic covalently attached liquid surfaces as coatings on cellulose substrate fabricating droplet based triboelectric nanogenerator. This new energy harvester represents a promising strategy for further application of smart and remote devices.
