Flexible perovskite photovoltaic cells (f‐PPCs) have demonstrated enormous potential in portable electronics due to the high power‐to‐weight ratio characteristic in outdoor and indoor ambient environment. However, the inherent mechanical endurance of f‐PPCs remains a major concern. Inspired by industrial strong adhesion coatings, herein, a porous nanoparticle layer is inserted into the buried interface...
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...
