Abstract [en]
This paper presents the first successful implementation of fully printed electronics for flexible and wearable smart multi-pad stimulation electrodes intended for use in medical, sports and lifestyle applications. The smart multi-pad electrodes with the electronic circuits based on organic electrochemical transistor (OECT)-based electronic circuits comprising the 3–8 decoder for active pad selection and high current throughput transistors for switching were produced by multi-layer screen printing. Devices with different architectures of switching transistors were tested in relevant conditions for electrical stimulation applications. An automated testbed with a configurable stimulation source and an adjustable human model equivalent circuit was developed for this purpose. Three of the proposed architectures successfully routed electrical currents of up to 15 mA at an output voltage of 30 V, while one was reliably performing even at 40 V. The presented results demonstrate feasibility of the concept in a range of conditions relevant to several applications of electrical stimulation. © 2022 by the authors

Funding details: Horizon 2020 Framework Programme, H2020, 825339; Funding details: European Commission, EC; Funding text 1: Funding: This research is part of the WEARPLEX project, funded by the European Commission’s Horizon 2020 research program under grant agreement number 825339.; Funding text 2: In this paper, we describe a novel prototype of an OECT device suitable for switching the pulses in electrical stimulation as well as demonstrate the first OECT-based multi-pad electrode developed within the WEARPLEX project [27], a research and innovation action financed under the Horizon 2020 program of the European Commission. The prototype features a fully printed demultiplexer circuit that can route the current from a single stimulation source to any of the electrode pads. When scaled, this concept would allow an exponential relation between the number of input leads and the number of supported electrode pads, providing a decisive leap from the currently available systems.
