However, current cleanroom-based microfabrication of OECTs hinders fast prototyping and widespread adoption of this technology for low-volume, low-cost applications. To address this limitation, a versatile and scalable approach for ultrafast laser microfabrication of OECTs is herein reported, where a femtosecond laser to pattern insulating polymers (such as parylene C or polyimide) is first used, exposing the underlying metal electrodes serving as transistor terminals (source, drain, or gate). After the first patterning step, conducting polymers, such as poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), or semiconducting polymers, are spin-coated on the device surface. Another femtosecond laser patterning step subsequently defines the active polymer area contributing to the OECT performance by disconnecting the channel and gate from the surrounding spin-coated film. The effective OECT width can be defined with high resolution (down to 2 \u00b5m) in less than a second of exposure. Micropatterning the OECT channel area significantly improved the transistor switching performance in the case of PEDOT:PSS-based transistors, speeding up the devices by two orders of magnitude. The utility of this OECT manufacturing approach is demonstrated by fabricating complementary logic (inverters) and glucose biosensors, thereby showing its potential to accelerate OECT research.", "doi": "10.1002/advs.202307042", "pmid": "38225700", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC11251563"}], "notes": [], "created": "2026-08-20T06:28:15.482Z", "modified": "2026-08-20T06:28:15.911Z"}, {"entity": "publication", "iuid": "d0787480eb844c68a8304e4a05170e87", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/d0787480eb844c68a8304e4a05170e87.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/d0787480eb844c68a8304e4a05170e87"}}, "title": "Mixing Insulating Commodity Polymers with Semiconducting n-type Polymers Enables High-Performance Electrochemical Transistors.", "authors": [{"family": "Zeglio", "given": "Erica", "initials": "E", "orcid": "0000-0002-6428-0633", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/e9f9fe3dcb5e4c9891c6f463c32a1679.json"}}, {"family": "Wang", "given": "Yazhou", "initials": "Y"}, {"family": "Jain", "given": "Saumey", "initials": "S", "orcid": "0000-0002-2810-2151", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/969496e3da804b54bea1cf345294433f.json"}}, {"family": "Lin", "given": "Yunfan", "initials": "Y"}, {"family": "Avila Ramirez", "given": "Alan Eduardo", "initials": "AE", "orcid": "0000-0001-9549-1516", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/900a9e8a82fd4708b025f91c613428fe.json"}}, {"family": "Feng", "given": "Kui", "initials": "K"}, {"family": "Guo", "given": "Xugang", "initials": "X"}, {"family": "Ose", "given": "Helena", "initials": "H", "orcid": "0009-0008-5546-4095", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/8eb950bfbdc4441b83d6cbd43bc2a8f4.json"}}, {"family": "Mozolevskis", "given": "Gatis", "initials": "G", "orcid": "0000-0001-7418-9123", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/59ff8fe8b6d74ecaab2998c57ad69032.json"}}, {"family": "Mawad", "given": "Damia", "initials": "D"}, {"family": "Yue", "given": "Wan", "initials": "W"}, {"family": "Hamedi", "given": "Mahiar Max", "initials": "MM"}, {"family": "Herland", "given": "Anna", "initials": "A", "orcid": "0000-0002-5002-2537", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/367ed0d139fe4136808b62ee61baa4f0.json"}}], "type": "journal article", "published": "2024-06-00", "journal": {"title": "Adv.

In contrast to organic electronics, bioelectronic devices such as the organic electrochemical transistor (OECT) rely on both electronic and ionic mobility for efficient operation, making it challenging to integrate hydrophobic polymers as the predominant blend component. This work shows that diluting the n-type conjugated polymer p(N-T) with high molecular weight polystyrene (10 KDa) leads to OECTs with over three times better mobility-volumetric capacitance product (\u00b5C*) with respect to the pristine p(N-T) (from 4.3 to 13.4 F V-1 cm-1 s-1) while drastically decreasing the amount of conjugated polymer (six times less). This improvement in \u00b5C* is due to a dramatic increase in electronic mobility by two orders of magnitude, from 0.059 to 1.3 cm2 V-1 s-1 for p(N-T):Polystyrene 10 KDa 1:6. Moreover, devices made with this polymer blend show better stability, retaining 77% of the initial drain current after 60 minutes operation in contrast to 12% for pristine p(N-T). These results open a new generation of low-cost organic mixed ionic-electronic conductors where the bulk of the film is made by a commodity polymer.", "doi": "10.1002/adma.202302624", "pmid": "38431796", "labels": [], "xrefs": [], "notes": [], "created": "2026-08-20T06:27:58.514Z", "modified": "2026-08-20T06:27:58.783Z"}]}
