A Programmable Semiconductor Containing Active Molecular Photoswitches Located in the Crystal's Volume Phase

open access: yesAdvanced Functional Materials, EarlyView.
A novel approach for the design of functional semiconductors is presented, which utilizes the excellent optoelectronic properties of layered hybrid perovskites and the possibility to introduce a molecular photoswitch as the organic spacer. This concept is successfully demonstrated on a coumarin‐based system with the possibility to change the bandgap ...

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

open access: yesAdvanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

A Printed Zinc‐Ion Microbattery with Extended Shelf Life and Durability for Energy Autonomous Sensors

open access: yesAdvanced Functional Materials, EarlyView.
We present a fully printed aqueous zinc‐ion microbattery (ZnIB) enabled by graphene‐decorated zinc anode and printed MnO@NC cathode using sustainable aqueous‐based ink formulations. The printed 3D electrodes ensure uniform zinc deposition, low overpotential, and long‐term stability.
