Advanced Materials Technologies, EarlyView.This study develops a 3D optical sensor formed by mechanical buckling and equipped with wireless communication for navigation. Off‐the‐shelf electronic components are assembled onto a flexible circuit board, followed by mechanical strain‐guiding, facilitating the integration of an out‐of‐plane sensing configuration with a signal processing module. This

Advanced Materials Technologies, EarlyView.A full‐domain 3D digital twin of a standing surface acoustic wave (SSAW) device on 128° YX LiNbO3 is developed and experimentally validated. The predictive power of the model is confirmed by electrical characterisation and laser Doppler vibrometry measurements, which show excellent agreement with simulations.

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel
Advanced Materials Technologies, EarlyView.The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.
