Electrophysiological sensors (electrodes) are used to collect complex electrophysiological signals, providing extensive information about the body's condition. Reliable signal acquisition necessitates stable skin-electrode interfaces prevent adverse effects arising from interface variations. Although incorporation of conductive adhesive layers can improve stability these interfaces, in array electrodes, layer may also cause short circuits and crosstalk. Here, we propose a general strategy for patterning electrodes based on electrochemically grafted polymers (EGAPs). Utilizing conductivity differences between sensing sites substrate material flexible spatial selective loading ionically be achieved through situ electrochemical reactions, thus realizing spontaneous patterning. This EGAP-based method allows rapid electrode surface modification just two steps. Furthermore, with EGAP acquired signals while improving quality collected effectively avoided crosstalk arrayed sites.

Toward Intrinsically Stretchable OLEDs with High Efficiency

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 21, 2025

Wearable electronics require stretchable displays that can withstand large and repeated mechanical deformation without failure. Intrinsically organic light-emitting diodes (ISOLEDs) operate under DC voltage provide promising candidates for wearable display applications. However, the lack of sophisticated materials processing techniques suitable ISOLEDs results in a significant deficit efficiency state-of-the-art compared to industrial standards. The design conducting semiconducting poses challenge because trade-off relationships between stretchability properties such as conductivity charge carrier mobility. To increase meet standards, strategies overcome these trade-offs must be developed. This perspective discusses recent progress challenges designing electrodes, materials, transport potential applications ISOLEDs. It provides useful guide this field develop efficient system-level integration.
