Performance‐Recoverable Closed‐Loop Neuroprosthetic System

Advanced Materials, EarlyView.
A self‐healing and stretchable bilayer (SSB) electrode with spontaneous performance recovery consists of a nanomembrane (closely packed aligned Pt‐coated Ag nanowires embedded in the self‐healing polymer) and a nanocomposite (Pt‐coated Ag flakes in the self‐healing polymer).

Monolithic Terahertz Topological Mach‐Zehnder Interferometer

Advanced Materials, EarlyView.
A monolithic topological Mach‐Zehnder interferometer (MZI) is presented, integrating the splitter, combiner, and waveguide arms on a single chip. The interferometric fringes exhibiting high on‐off contrast with extinction ratios over 20 dB are achieved by utilizing tailored unit cells that facilitate interface‐dependent out‐of‐plane radiation losses ...
