Nanotechnology Now - Press Release: Improving the efficiency of nanogenerators that harvest static electricity

Triboelectric energy is the scientific term for static electricity, or the energy that is created when two surfaces rub against each other. Electrons are exchanged between the two surfaces, charging one of the surfaces after they are separated. For example, if a balloon is rubbed against hair, it will cling to a wall. Or if clothes in the dryer rub together, you may see sparks as you pull them apart. Triboelectric generators are mechanical energy harvesters that can generate electricity from two surfaces rubbing against each other. These tiny power generators can be used to power wearable electronic devices, sensors, and other advanced technologies.
