a Optical transmittances of bioinspired heater electrode at different sheet resistances. Inset shows the relationship of sheet resistance at different Ag nanowire loading. Three independent measurements were done, and the error bars show the standard deviation. b Camera images displaying the transparency of the bioinspired heater electrode at different sheet resistances.
