Printable Inks Made of Conductive 2D Materials Beyond Graphene for Micro-Electrochemical Devices
Wearable technology, the most important part of Internet of Things (IoTs), is facing a rapid development. The main component of the wearable electronics is the sensor, able to provide useful insights into the performance and health of individuals. Early efforts of wearable sensors is mainly used for sensing physical signals that monitored mobility and vital signs, such as steps, calories burned or heart rate. Electrochemical sensor (ECS), an integrated device that provides analytical information, either quantitative or semi-quantitative, using a biorecognition strategy involving an electrochemical transducer, provides a powerful analytical technique able to measure broad range of important biochemical compounds such as glucose, uric acid, and amino acids. This project aims at bringing the much-needed step change in flexible and wearable electronics by developing a new industrially driven inkjet printing technology for the definition of electronic devices for sensing. The key challenge is therefore to develop printable ink formulations with highly tuneable property, functionality and printability suitable for sensing. This project aims at developing printable ink formulations, exploiting 2D materials beyond graphene with properties suitable for the fabrication of a wide range of printed sensors. This research ranges from material development to target applications, hence the results are expected to raise strong interest from both the research community and industry.

Project objective
In the framework of Internet of Things (IoTs), sensors able to monitor biochemical compounds are extremely important. Electrochemical sensors (ECSs) are the most promising tools to provide analytical information. Current challenge of ECS is the fabrication requirement changing from traditional rigid and planar substrates to flexible/wearable substrates for integrated portable devices, as well as the electrochemical reactor shift from conventional three electrodes to micro-fluidic system in order to make sensors smaller. Inkjet printing is a cost-effectiveness technology to create micro-ECS on versatile substrates with noncontact and precisely patterning. Despite various advantages of this technique, challenges remain in the development of printable ink formulations with suitable properties for target devices. Two dimensional (2D) materials are attracting increasing interest because of their maximally exposed active sites and small diffusion paths within ultrathin nanosheets, which effectively facilitate charge transfer in the electrochemical sensing activities. 1T phase transition metal dichalcogenides (TMDs) and conductive layered Metal Organic Frameworks (MOFs) have been demonstrated to have distinct electrochemical and electronic properties, while they have not yet received attentions for use in printed devices. The various metal sites, diverse structure and tuneable nature of these materials have great potential for high selective and sensitive monitor. This project aims at developing printable ink formulations based on 1T TMDs and conductive 2D MOFs to fabricate micro-electrochemical sensors on flexible substrates for biometric parameters determination. Highly selective, efficient and low cost devices are supposed to be achieved. This research ranges from material development and device fabrication to proof-of-concept applications, hence the results are expected to raise strong interest from both research community and industry.
