Hydrogel Paper Power Improved by Origami

Hydrogel Paper Power Improved by Origami
Origami and electric eels have inspired a hydrogel paper that could lead to devices able to generate power inside the body.

A team from the University of Fribourg created the device by 3D-printing an array of around 2500 gels onto two regular paper-sized plastic sheets, which they then folded into a Miura-ori fold. This arrangement allowed the gels to connect with a large contact area at the same time, creating a structure similar to the eel’s cells and producing a higher current than previous versions of the technology.
