If Triboelectrics could become a source of power for electronic devices would it be of interest?

Electropages says: Triboelectrics is the generation of electricity from friction and it could become a new power source for electronic devices. 

The friction could be as simple as a finger swiping across a smartphone’s glass screen, walking, the friction of shoe upon pavement, or friction between textile fibres, and they could all become sources of power.
