Abstract:

Traditional hydrogels made of polyacrylamide or chitosan have relative smaller tensile strength and higher Youngâ??s module (lower elasticity) compared to highly stretchable elastomers. This has hindered the development of wearable sensors using traditional hydrogels. The low durability of these hydrogels also inhibits long-term usage of these sensors. This work focuses on the development of sensors based on a recently discovered tough hydrogel that are made of a hybrid of polyacrylamide and alginate. This new type of hydrogel may serve as a remarkable material for chemical and biological sensing with high elasticity and durability. We report to utilize the tough hydrogels to validate the sensing performance, especially the stability and the durability of these hydrogels.
