To facilitate nasotracheal intubation a conductor made from esophageal tube is recommended. The advantage of this conductor is that the tube could be directed into the trachea without intubation forceps. No special material is required and it is available for any anesthesiologist.

Developing high-performance n-type organic mixed ionic-electronic conducting (OMIEC) polymers with simple structural motifs is still challenging. We show that high-performance, low-threshold-voltage n-type OMIEC polymers can be achieved using a simple diketopyrrolopyrrole unit flanked by thiazole groups, which is functionalized with glycolated side chains. Interestingly, the regiospecific sp2-N position in the repeating unit's thiazole governs the polymer chains' solvation and molecular packing.

Understanding charge transport in organic mixed ionic-electronic conductors (OMIECs) is crucial to improve the performances of bioelectronic and neuromorphic devices. Recent studies reveal that the amplification of electrical signals in organic electrochemical transistors is determined by the volumetric capacitance c and electronic mobility μ of OMIEC channels, but how material parameters impact on the signal propagation speed and energy dissipation remains unclear. To address this issue, we combine electrical measurements of the phase velocity in microstructured OMIEC channels with local measurements of ionic displacements with modulated electrochemical atomic force microscopy.

Compression strongly degrades the electrical conductivity of the liquid-metal-based circuits because the liquid state is prone to be squashed. Here, a new compressible and stretchable biphasic liquid-solid self-healing circuit is proposed by filling GalnSn-BilnSn biphasic metal into micropillar-embedded channels. The underlying BilnSn solid alloy layer serves as a compression resistance layer, while the upper GalnSn liquid metal layer enables the real-time filling of the cracks in the solid layer under large deformations, resulting in autonomous self-healing and maintenance of conductivity under both stretching and compression.

Such devices typically require leads of significant length to deliver stimulation. The use of long leads in combination with an implantable pulse generator often means that there is a significant risk of radiofrequency energy coupling with the leads when patients receive MRI scans.

Materials that effectively facilitate the transport of ionic and electronic charges are crucial for advancing technological innovations in next-generation energy storage devices. This work proposed a new class of high-performance mixed ionic-electronic conductors (MIECs) in graphite intercalation compounds with the composition XC (X = {Ca, Sr, and Ba}) using molecular dynamics based on machine learning force fields combined with first-principles calculations. The calculated mean squared displacement and radial distribution functions indicate that CaC, SrC, and BaC transition to the superionic state at temperatures of 1500, 1800, and 2100 K, respectively.
