Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Conformable Ferrimagnetic Tattoo Electrodes for Plant Electrophysiology

open access: yesAdvanced Materials Technologies, EarlyView.
The newly developed ferrimagnetic tattoo electrode is capable of measuring plant electrophysiological activity outside the Faraday cage. Its ability to adhere without damaging the plant tissue allows long‐term recordings. This premise opens new avenues for in‐field monitoring of plant health through electrophysiology.
