Femtosecond micro-supercapacitors on a single leaf could easily be applied to wearable electronics, smart houses, and IoTs. A KAIST research team has developed a graphene-inorganic-hybrid micro-supercapacitor made of leaves using femtosecond direct laser writing lithography. The advancement of wearable electronic devices is synonymous with innovations in flexible energy storage devices. Of the various energy storage devices, micro-supercapacitors have drawn a great deal of interest for their high electrical power density, long lifetimes, and short charging times.

However, there has been an increase in waste battery generation with the increases in the consumption and use of electronic equipme...
