The new patch has a pattern of artificial sweat ducts, similar to the pores in human skin. Authors of the development
The kirigami design also helps the adhesive fitto human skin as it stretches and bends. This flexibility, combined with the material's ability to resist sweat, allows it to keep a person's health in check for extended periods of time. This was not possible before.
The new electronic skin is equipped with sensors formonitoring temperature, hydration, UV exposure and heart rate. During the experiment, the patch obtained reliable measurements even during physical activity, when the user sweated heavily.
The new development is a step toward creating long-lasting smart skin that can track daily vital signs or the progression of skin cancer and other conditions.
The results of the study are published in the journal Science Advances.
