Stretchable Electronic Facial Masks for Skin Electroporation

A stretchable electronic facial mask (SEFM) for skin electroporation by transdermal drug delivery is introduced. The SEFM exhibits characteristics of reusability, water‐resistant, low cost, and portability. To achieve these objectives while maintaining satisfactory mechanical and electrical performance of the device, two main areas are innovated: (1) Grinding and doping modification of conductive ink to enhance its adhesion to silicone and increase conductivity through material research, as well as mechanical structure design for stretching stability of conductive ink electrodes. (2) Doping modification of high‐temperature vulcanizes silicone to address the issue of increased resistance during encapsulation due to the swell of conductive ink. The SEFM designed with these innovations, is validated in rat experiments, demonstrating a 3–4 times increase in drug intake compared to the control group without skin electroporation. Safety is confirmed, and the promotion of niacinamide drug delivery is verified in human volunteers. The materials‐modified conductive ink and conductive silicone proposed in SEFM can be employed in other flexible wearable devices, and this platform has the potential for future integration of additional components to achieve expanded functionality and productization. A stretchable electronic facial mask (SEFM) for skin electroporation by transdermal drug delivery, enabling the delivery of drugs such as sodium hyaluronate (SH), aloe powder, β‐glucose, and d‐panthenol. The SEFM significantly enhances drug intake, with a 3–4 times increase. This platform holds the potential for future integration of additional components to expand its functionality and facilitate product development.
