Functions as a conducting medium for flexible electronics applications

With the ability to generate and conduct electricity, the hydrogel can also be used as conductive, removable ink on electric circuit boards. The hydrogel can be washed off with vinegar. It can also be reused, which helps in the recycling of printed circuit boards and reduces electronic waste.
