Power Source Printed from Cyanobacteria

Researchers in London have developed means to print cyanobacteria and conductive carbon nanotubes onto paper. The printed cyanobacteria creates small amounts of electricity through photosynthesis, which can be used to power a small sensor. This innovation in the field of microbial photovoltaics could be used to make cheap and biodegradable sensors entirely composed of paper.
