Description | Our contribution to the PNEUMACRIT project involved designing organic electronic circuits and components for a impedance tomography imaging system. Towards that we developed and tested novel materials, designed and fabricated new devices. Work was carried out in extensive collaboration with the lab of Prof. Andreas Demosthenous (AD), in particular with PhD student Mrs. Farnaz Fahimi Hanzae. The main focus of the project was developing an organic-electronic transistor-based amplifier for electrical impedance tomography. We fabricated organic electrochemical transistors (OECT) of varying parameters, which we supplied to the lab of AD, for the purpose of constructing a model to inform design of complex voltage amplifier circuits (Hanzaee et al., 2021) . After optimizing the design to a more suitable form factor for prototyping, and integrating with additional discrete components, we are currently preparing a manuscript describing differential amplifiers with voltage gain of ~5, based on OECTs. We additionally established a collaboration with industry, Heraeus AG GmBH, through which we tested materials for self-adhering conductive polymer electrodes (Dimov et al., 2022). The materials showed adhesive properties similar to neonatal medical tape, suggesting their potential use in neonatal cutaneous electrophysiology. This publication was highlighted by the editor of Applied Physics Reviews) Additionally, in order to make our devices easier to manufacture at scale, we explored different ways of depositing metal films at ambient conditions, to avoid the use of slow and costly high-vacuum procedures. We discovered a process to deposit gold tracks onto polymer substrates under ambient conditions. Currently, we are preparing to submit a manuscript on the subject (Dimov et al. 2023 - in preparation). Lastly, we published an extensive review on conducting polymers for neural applications, in Chemical Reviews. |
Exploitation Route | Advances achieved in this project in the areas of - new materials for cutaneous electrodes - transistor architectures for wearable applications will potentially have several applications. For example the wearable electrodes developed will be of use in other health monitoring scenarios, for example recording of heart, brain and muscle activity. These are applications that are being considered for at-home monitoring of the elderly and at-risk individuals. The transistor architectures are generic and can be used in implantables to amplify the weak signals obtained in neurotechnology applications, as well as for implants in plants and trees, which are being developed for precision agriculture. Finally, the internet-of-things is another area that will benefit fro advances in organic electronic circuitry. |
