Pollen-based 'paper' holds promise for new generation of natural components

Scientists have created a paper-like material derived from pollen that bends and curls in response to changing levels of environmental humidity. The ability of this paper made from pollen to alter its mechanical characteristics in response to external stimuli may make it useful in a wide range of applications, from artificial muscles to sensors. Combined with digital printing, it may hold promise for the fabrication of a new generation of programmable natural actuators.
