Compact size dipole antenna

Electronics Letters, 2008
A novel wideband planar dipole antenna is proposed. This antenna has a simple structure and compact size. For verification, the newly proposed structure was fabricated and measured. It is shown that the return loss of the antenna between 3.0 and 7.5 GHz is better than - 10 dB. The radiation performance is good over the whole frequency band.

Charge‐Induced Morphing Gels for Bioinspired Actuation

Advanced Functional Materials, EarlyView.
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...
