Food‐Based Edible Wireless Sensing Device with Isotropic Electromagnetic Response for Gastrointestinal Monitoring

Advanced Materials Technologies, EarlyView.
A sensor is fabricated that reflects electromagnetic waves wirelessly using only edible materials. The substrate is made of edible materials such as sugar and starch, and the electrodes are made of gold. This sensor has isotropic electromagnetic wave characteristics in response to rotation.

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

Advanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Design and Fabrication of High Dielectric GRIN Lens for a Directive Antenna Using a Hybrid Filled Voxel Additive Manufacturing Technique

Advanced Materials Technologies, EarlyView.
Hybrid‐filled voxel AM enables integration of high‐permittivity materials into additively manufactured devices. Using this approach, a graded refractive index (GRIN) lens is demonstrated, achieving a 50% antenna size reduction with enhanced directivity.
