Programmable Crack Networks for Wide‐Range and Reversible Strain Sensing in Vertically Oriented van der Waals Molybdenum Disulfide Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
Vertically oriented van der Waals MoS2 thin films enable a mechanically programmable crack network for strain sensing. The initial mechanical programming protocol establishes a programmed crack configuration along weak interlayer and interdomain interfaces.

Unlocking Terahertz Steganography: Authentication of Hidden Images in Flexible Media

open access: yesAdvanced Materials Technologies, EarlyView.
Hidden information in multilayered devices, such as steganographic portraits, is detected and authenticated using reflection‐mode terahertz time‐domain imaging. Image reconstruction relies on a dedicated figure‐of‐merit obtained by integrating the signal intensity over the time‐window associated with the reflection from the metallic mirror backing the ...

Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control

open access: yesAdvanced Materials Technologies, EarlyView.
A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...
