Project description
Photo-patternable electrolytes for future of brain-computer interfaces
The concept of brain-computer interfaces has increasingly appeared in the fiction and technological ambitions of organisations and researchers. These interfaces provide improved and easier control over devices. However, developing advanced brain-computer interfaces requires fully integrated electronic circuits capable of processing highly personalised and localised signals from the nervous system and living tissue without endangering them. With the support of the Marie Skłodowska-Curie Actions programme, the PSOECNs project will design and demonstrate a photo-patternable solid electrolyte to facilitate the development of solid-state organic electrochemical transistors. This technology is promising and crucial for interfaces, which have been strictly limited by various challenges until now.
Objective
Future advanced brain-computer interfaces, wearable and implantable bioelectronic devices, prosthetics, and intelligent soft robotics will require the ability to process signals in a highly personalized and localized manner, which will involve fully integrated electronic circuits within the nervous system and other living tissues. To achieve this goal, it is imperative to develop energy-efficient intelligent electronics that have minimal device/circuit complexity and ion-based transducing and operating mechanisms akin to those observed in biology. The use of Silicon-based devices and circuits presents several limitations. Organic electrochemical transistors (OECTs) represent a rapidly advancing technology that plays a pivotal role in the development of next-generation bioelectronic devices. However, a notable limitation of OECTs is their typical operation in aqueous electrolytes, which can lead to undesired crosstalk between different devices on the same substrate, impeding their seamless integration into large-area arrays. Therefore, it is hard to develop neural networks based on the current OECTs. Solid electrolytes offer a promising solution to these challenges. In this proposal, I design a photo-patternable solid electrolyte to develop solid-state OECTs. The aim is to directly pattern the electrolyte using sequential ultraviolet light-triggered solubility modulation. We plan to use UV-sensitive PEGDA to directly pattern the hydrogel without requiring photoresist or lift-off processes. The PEGDA network will be covalently crosslinked after UV exposure to form a hydrogel network. The strong intermolecular interaction between the two networks will allow the UV-exposed regions to resist subsequent water development, while the UV-unexposed regions will remain water-soluble. This approach will enable the creation of smaller-size, large-area processing OECT devices, ultimately facilitating the development of OECNs with sizes approaching that of biological neurons.
