4D‐Printed Soft and Stretchable Self‐Folding Cuff Electrodes for Small‐Nerve Interfacing (Adv. Mater. 12/2023)

Self‐Folding Electrodes In article number 2210206, Lukas Hiendlmeier, Francisco Zurita, Bernhard Wolfrum, and co‐workers present a new method for fabricating small, soft, and stretchable cuff electrodes that fold and change shape when submerged in an aqueous environment. Just like a hand closes its fingers when grasping, these structures fold and wrap around peripheral nerves, greatly simplifying the process of nerve interfacing at a small scale.
