Electronics Letters, 2010 An ultra-wideband loop antenna is proposed that is based on a wavelength loop antenna and a slot antenna. The self-complementary principle is applied to the designed ultra-wideband antenna. The antenna operates as a loop antenna in the low frequency band (0.3-1-GHz) and as a slot antenna in the high frequency band (1-14.2-GHz).

Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics
Advanced Materials, Volume 37, Issue 13, April 2, 2025.Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.
