We developed moisture-enabled electricity generation materials by loading polydopamine-modified nonwoven substrates with cyanobacteria-sodium alginate-chitosan hydrogels. Under ambient conditions, the device produced an output of 0.48 V and 2 μA. Polysaccharides and proteins released from disrupted cyanobacteria facilitated charge separation. When connected in series, the materials were able to power light-emitting diodes.
