Ten-Hour Stable Noninvasive Brain-Computer Interface Realized by Semidry Hydrogel-Based Electrodes

Junchen Liu et al.

Summary: In this study, a semidry EEG electrode, using silver-nanowire/PVA hydrogel/melamine sponge materials, was developed for long-lasting monitoring of EEG signal. The electrode has high conductivity, long-term effectiveness, and biocompatibility, and can reduce scalp-electrode impedance and improve wearing comfort. The experiment demonstrated that the accuracy of the new electrode is comparable to that of conventional electrodes in long-term applications measuring motion-onset visual evoked potentials.

Achieving High Thermoelectric Performance and Metallic Transport in Solvent-Sheared PEDOT:PSS

Allison C. Hinckley et al.

Summary: Polymer-based materials have great potential for thermoelectric applications, though limited by poor electrical properties. By utilizing solution-shearing deposition and directionally applied solvent treatments, high power factors exceeding 800 mu W m(-1) K-2 can be achieved in PEDOT:PSS thin films. Structural alignment of PEDOT chains and larger-sized domains play a crucial role in enhancing electrical conductivity. Further improvements to power factor are expected through device geometry and postdeposition solvent shearing optimization.
