Perspiration-Wicking and Luminescent On-Skin Electronics Based on Ultrastretchable Janus E-Textiles

Abstract

Stretchable electronics have attracted surging attention for next-generation smart wearables, yet traditional flexible devices fabricated on hermetical elastic substrates cannot satisfy lengthy wearing comfort and signal stability due to their poor moisture and air permeability. Herein, perspiration-wicking and luminescent on-skin electrodes are fabricated on superelastic nonwoven textiles with a Janus configuration. Through the electrospin-assisted face-to-face assembly of all-SEBS microfibers with differentiated diameters and composition, porosity and wettability asymmetry are constructed across the textile, endowing it with antigravity water transport capability for continuous sweat release. Also, the phosphor particles evenly encapsulated in the elastic fibers empower the Janus textile with stable light-emitting capability under extreme stretching in a dark environment. Additionally, the precise printing of highly conductive liquid metal (LM) circuits onto the matrix not only equips the electronic textile with broad detectability for various biophysical and electrophysiological signals but also enables successful implementation of human–machine interface (HMIs) to control a mechanical claw.

“…The electrospinning parameters were the same as the previous reports. [ 42 ] Specifically, perfluorosilane‐treated copper mesh (mesh number: 400) was used as the deposition substrate.…”

Hemp-Based Electronic Textiles for Sustainable and Wearable Applications

“…The demand for wearable electronics is increasing and contributes to the generation of large electronic waste. Around 54 million metric tons of electronic waste was generated globally in 2019. − The maintenance, replacement, and the limited lifetime of these electronics remain challenging for waste management.…”

Highly Antibacterial and Self-Healing Janus Fabric for Effective Body Moisture/Thermal Management and Durable Waterproof

“…Moreover, fabrics play a crucial role in the process of heat transmission between the body and its surroundings when humans are exposed to outdoor environments. − During periods of extreme exercise or direct exposure to intense sunlight radiation, the body’s skin temperature experiences a rapid increase due to the production of sweat on the body surface. , Without efficient sweat transportation and the ability to dissipate excessive heat, the substantial production of perspiration can readily result in heat stroke, dehydration syndrome, and other heat-related diseases. − Despite advancements in many personal moisture management fabrics, they continue to lack the ability to effectively resist external droplets. High-quality waterproof fabrics enhance the ease of travel by protecting against rain and snow.…”
