Large‐Area Printed PEDOT:PSS Shielding and Frequency Selective Surface (FSS) on Textiles
Advanced Materials Interfaces, EarlyView.An all‐polymer e‐textile frequency selective surface (FSS) can present controlled shielding, presenting a competitive alternative to metal‐based inks. The results show how PEDOT: PSS‐based e‐textiles could be applied in RF devices for future wearable applications.

Optimization of planar periodic leaky-wave antennas by selective surface-wave suppression [PDF]
, 2014 Planar periodic ‘bull-eye’ leaky-wave antennas are investigated for two-sided frequency beam scanning and broadside radiation at microwave and millimeter-wave frequencies. In particular, the ground plane and the radial configuration of the structures are

Advanced Materials Interfaces, EarlyView.As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...

Advanced Materials Technologies, EarlyView.We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...
