Water stable and matrix addressable OLED fiber textiles for wearable displays with large emission area

Organic light-emitting diode(OLED)fibers with favorable electroluminescence properties and interconnectable pixel configurations have represented the potential for wearable electronic textile displays.Nevertheless,the current technology of OLED fiber-based textile displays still leaves to be desired due to several challenges,including limited emission area and lack of encapsulation systems.Here we present a fibrous OLED textile display that can attain a large emission area and long-term stability by implementing addressable networks comprised of integrated phosphorescence OLED fibers and by designing multilayer encapsulations.The integrated fiber configuration offers decoupled functional fiber surfaces for an interconnectable 1-dimensional OLED pixel array and a data-addressing conductor.Tailored triadic metal/ultrathin oxide/polymer multilayer enables not only the oxygen/water permeation inhibition but also the controllable conductive channels of dielectric antifuses.Together with reliable bending stability,the long-term operation of OLED textiles in water manifests the feasibility of the present device concept toward water-resistant full-emitting-area fibrous textile displays.

Neuromodulation of the peripheral nervous system:Bioelectronic technology and prospective developments

The peripheral nervous system(PNS)is a fascinatingly complex and crucial component of the human body,responsible for transmitting vital signals throughout the body's intricate network of nerves.Its efficient functioning is paramount to our health,with any dysfunction often resulting in serious medical conditions,including motor disorders,neurological diseases,and psychiatric disorders.Recent strides in science and technology have made neuromodulation of the PNS a promising avenue for addressing these health issues.Neuromodulation involves modifying nerve activity using a range of techniques,such as electrical,chemical,optical,and mechanical stimulation.Bioelectronics plays a critical role in this effort,allowing for precise,controlled,and sustained stimulation of the PNS.This paper provides an overview of the PNS,discusses the current state of neuromodulation devices,and presents emerging trends in the field,including advances in wireless power transfer and materials,that are shaping the future of neuromodulation.
