Det mønster af ledende materialer er en af ​​de første skridt i fremstillingen af ​​funktionelle elektroniske enheder. Dette kan blive udfordrende, som fremstillingsprocessen skal tage hensyn til de kemiske og fysiske egenskaber af sådanne materialer, og processen flow behov for at overveje materialet cross-kompatibilitet mellem de fabrikationstrin. I mikrofabrikation af organiske elektroniske enheder, disse to aspekter er endnu større på grund af den meget reaktive natur økologi. Men i dag, organiske mate...

Feltet af bærbare elektronik er et hurtigt voksende marked forventes at være værd 50 milliarder euro i 2025, over tre gange det nuværende marked. Den største udfordring for de nuværende bærbare enheder er, at indgribende solid elektroniske vedhæftede begrænse brugen af ​​etablerede enheder i bærbare systemer. Brug tekstiler, der allerede er til stede i hverdagen er en meget attraktiv og enkel tilgang for at undgå denne begrænsning. På grund af sin elastiske evne, nogle dele af tøj, som vi bærer er naturligvis i tæt kontakt med huden. Mange eksempler på smart tøj til rådighed på markedet i dag, er baseret på tynde, plast skærme, tastaturer og lyskilde enheder indlejret i tekstiler, der forbinder elektronik med mennesker i et moderigtigt måde en. I sport praksis, sundhedsovervågning afhængig tekstilelektroderne, som tilbyder komfortable alternativer til almindeligt anvendte selvklæbende elektroder og metal armbånd. Her, ledende fibre erdirekte integreret med strækstoffer for at forhindre hudirritation og andre ubehageligheder under udvidet slid. Derudover tekstiler tilbyder en række muligheder for at integrere krumning sensorer til at fange bevægelse 2, at integrere shear sensorer til udvikling af funktionelle robot aktuatorer 3, og bestemt til at integrere biosensorer gennem påvisning af en analyt i sved 4. Moderne wearable teknologi bygger på kulstof-baserede halvledermaterialer, der leverer elektroniske enheder med unikke egenskaber. Den &quot;bløde&quot; karakter af økologi giver bedre mekaniske egenskaber for sammenknytning med den menneskelige krop i forhold til traditionelle solid-state elektronik. Denne mekanisk kompatibilitet, parret med mekanisk fleksible substrater, muliggør anvendelse af ikke-plane formfaktorer i indretninger såsom tekstiler. Anvendelsen af ​​organiske forbindelser er også relevant i biovidenskab på grund af deres blandede electronic og ionledningsevne 5. Desuden, organisk halvledende og optoelektroniske materialer bemyndige en lang række funktionelle enheder med display, transistor, logik, og magt kapaciteter 6, 7, 8, 9. Den største vanskelighed ved fremstillingen af ​​sådanne organiske anordninger er den styrede aflejring af funktionelle materialer på ikke-plane overflader på tekstiler. Konventionelle microfabrication teknikker er primært begrænset af uforenelighed af depositionen processen med den strukturelle dimensionalitet af tekstile substrater. Her beskriver vi en enkel og skalerbar fabrikation protokol, der muliggør den selektive aflejring af ledende polymerer om strukturerede tekstiler. Den præsenterede proces muliggør fremstillingen af ​​bærbare og konforme elektroniske enheder. Den fremgangsmåde er baseret på mønsterdannelse af commercially tilgængelige ledende polymer poly (3,4-ethylenedioxythiophene): poly (styrensulfonat) (PEDOT: PSS) og et elastomert stencil materiale polydimethylsiloxan (PDMS) på tekstil. Denne kombination giver mulighed for effektiv indeslutning af den vandige PEDOT: PSS opløsning, samt for opbevaring af de bløde og strækbare egenskaber af tekstiler. Denne enkle og pålidelig fabrikation metode baner vejen for fremstilling af en bred vifte af elektroniske enheder direkte på tekstiler i en omkostningseffektiv og industrielt skalerbar måde.

a simple and scalable fabrication method for organic electronic devices on textiles

Today, wearable electronics devices combine a large variety of functional, stretchable, and flexible technologies. However, in many cases, these devices cannot be worn under everyday conditions. Therefore, textiles are commonly considered the best substrate to accommodate electronic devices in wearable use. In this paper, we describe how to selectively pattern organic electroactive materials on textiles from a solution in an easy and scalable manner. This versatile deposition technique enables the fabrication of wearable organic electronic devices on clothes.

Traditionelle metoder til påføring farver eller mønstre til tekstiler afhængige aftagelige blænding lag for at tillade selektiv aflejring af farvestoffer. I figur 1, viser vi en tilpasning af en sådan tilgang til mønstret af PEDOT: PSS elektroder på tekstiler. Som maskerende lag, brugte vi hydrofob polydimethylsiloxan, som kan tilbageholde ikke-styrbare diffusion af det vandige PEDOT: PSS opløsning. Desuden kan blødheden og strækbarhed af strikkede og vævede ...
