RF-based wireless power harvesting

In a world of wonder and delight, There are devices shining so bright, They gather energy from the air, To power gadgets beyond compare. From the sun's rays up in the sky, To the wind that blows as time goes by, Energy harvesters, oh so small, Capture power, one and all. They use the heat that's all around, And the waves that crash with a mighty sound, From salinity gradients, they take, Every source of energy they make. With wireless sensors, they're always aware, Of the world and its wonders, everywhere, Wearable electronics, they can adorn, And monitor conditions from dusk till morn. So let's celebrate these clever devices, That capture energy from all the vices, They turn the ambient background into power, And make our world brighter every hour. Random page: Uow.edu.au
