Humidity responsive fibersThe University of Akron
Fibers contract and relax in response to humidity
Fibers contract and relaxspiders
Dragline silk fibers in spider webs help maintain web tension under weight by contracting and relaxing in response to humidity.
Spring directs spore dispersal in low humidityhorsetail
The elaters of horsetail plants aid spore dispersal by coiling and uncoiling in response to humidity.
Humidity changes exoskeleton colorHercules beetle
The exoskeleton of the Hercules beetle changes from green to black with increasing humidity using thin film interference by reversible modification of layer thickness.
