This paper describes a biomaterial that was created to mimic the function and properties of human skin. PSeD-U elastomers were created by designing a unique covalent hybrid crosslinking structure with hydrogen bonds that increase the toughness and strength of the material. One of the properties that was measured was tear resistance. The PSeD-U20-12h elastomer was found to be able to stretch up to 3.5 times and had a high tearing energy which indicates the energy dissipation of hydrogen bonds. The degradation rate of this material was also much slower, again indicating the effects of the strong hydrogen bond. The discovery of this material is important for applications such as pressure sensors in human/machine interactions, wearable electronics, or medical implants.
