WP1 Coordination and management
The aim of this deliverable is to describe the early project management activities which enabled successful project kickoff in May of 2020. Furthermore, it documents the initial project communication activities mostly related to informing the public about the project starting and roles different organisations will have in it.
Due to the travel limitations induced by COVID-19 pandemic the kick-off meeting was held in a virtual environment through a teleconference. Its organization and approval by the EC were predated by extensive work on risk assessment by each consortium member and as a group, as well as creation of a robust risk mitigation plan for the initial stages of the project. Once the project started the news was spread on the consortium member’s websites, social networks and in the local media.
Despite the challenges imposed by the pandemic the project has successfully started in May 2020 as originally intended. The consortium overcame the initial obstacles through collaboration and dedication to the common vision. The kick-off meeting was held and communicated to the public.
On this link you can find all the press releases, articles and media content related to consortium members and the project up to now.

The purpose of this deliverable is to present the list of co-development guidelines that have been drafted, drawing upon the valuable experience gained throughout the project. These guidelines serve as a comprehensive framework for fostering collaboration and interdisciplinary cooperation between technical partners and practitioners working in hazardous conditions.
The co-development process started with the questionnaires almost immediately upon the project start, where we identified the most important physiological variables, as judged by the first responders, and we checked sensors already available from the technological partners, for the Alpha demonstrator setup. The process has been continued during the whole development of the SIXTHSENSE project by means of meetings before and after the field tests and questionnaires submitted to the practitioners. After the tests of the Beta demonstrator we focused our attention on the existing references on guidelines for the co-development process in the field of first responders.
A set of 12 guidelines for establishing a successful co-development in a multidisciplinary environment have been drafted:Defining roles and responsibilities
- Engaging stakeholders early
- Clear definition of goals
- Establishing a collaborative environment
- Adopt a user-centric design approach
- Consider Usability and Ergonomics
- Consider Safety and Mistakes impact
- Collect end-users’ feedbacks and integrate them with technical possibilities
- Iterating and Prototyping
- Documenting the co-development Process
- Ethical Considerations
- Sharing Knowledge and Results
By leveraging the knowledge and expertise accumulated during our project, we aim to facilitate the successful implementation of co-development processes, ensuring the development of innovative solutions that address the unique challenges faced by practitioners in hazardous environments.

The main aim of this deliverable is to report the protocol of upscaling fabrication of all sensors developed along the execution of the project, preferable all integrated in one unique device. The key aspects of fabrication protocol are described as well as materials used for the fabrication of different devices. In addition, the costs of production are evaluated.
Final sensor platform integrating 6 sensors and 4 iontophoretic extraction systems
The final device integrates three different chemical sensors (cortisol, lactate and Na+), two of them with sensing phases based on biological recognition elements. The fabrication of the final device consists of two different manufacturing procedures. The first one is carried out using thick film technology. In this case the electrodes with different designs, that have been optimized during the project, are screen-printed on PET substrates using silver, carbon and PEDOT:PSS inks. After that, the second procedure is aimed to fabricate the different sensing phases. In this case the fabrication is carried out using inkjet printing technology. Finally, the cost of production is about 25 euros/device for high scale production, being this cost the minimum value that currently we can achieve due to the high cost of anti-cortisol antibodies.

Aim
This deliverable summarizes the design, working principle, preliminary investigations, fabrication and characterization of a pumping mechanism which allows for sucking in a liquid into the sensor channel.
Approach
In contrast to the technology envisioned in the proposal phase, a novel concept for a suction pump was developed based on an ultrathin electroosmotic pump. This allows for a very flat and tiny device. The electroosmotic pump is based on a gold-coated track-etched membrane. For integration into the sensor device, the membrane is contacted by a ring electrode on the sensor substrate and an electrode-inlay on the opposite side, which is contacted back to the sensor substrate, so that only one connector is required.
Results
Final setup. a) Front and back view. b) Size comparison. c) Channel filled with blue water
The assembled sensor-pump setups were finally pre-filled with water and then pumped based on the results of the preliminary investigations.

Aim
The aim of deliverable 4.5 is to develop a way to sense analytes at very small flow rates. In the final application the interstitial fluid (ISF) to be measured is only available in small volumes and it can only be taken out of the skin with low speed (few µl/h). Since the enzymes in the sensor consumes lactate molecules, the actual concentration at the sensor becomes lowered for low flow speeds. Therefore a sensor setup is necessary that reduces the lactate consumption while keeping the sensitivity for the lactate in the ISF at a level useful for the transmitter electronics used. Reducing the sensitivity means reducing the lactate consumption and therefore decreases the minimum useful flow rate.
At low speeds also the effect of a chemical cross-talk within the sensor flow cell is greater and the H2O2 produced by the enzymes accumulates to higher levels and creates higher readings at the blank electrode of the sensor – in case the release of H2O2 into the ISF stream is not prevented by a catalase membrane topcoat. While without such catalase membrane the reading of the chemical cross talk at the blank electrodes can be used as an indicator of such ultra-low flow rates. An indication that is not possible by other means of lflow rate measurement.
Deliverable 4.5 is therefore an important step towards the final application.
Approach
The approach consists of these parts:
- Depositing functional membranes to the sensor electrodes by first adding molecular sieves by electropolymerization to the electrodes.
- Subsequently the enzymatic and diffusion control membranes will be dispensed and afterwards UV-cured.
- To minimize the lactate consumption and cross-talk the active area of the membranes should be as small as possible. The base idea is therefore to have small slits under the flow channel of the sensor. The slits form the cavity to hold the membranes as depicted in figure 5 creating band like narrow electrodes.
The challenge is hereby to optimize the membranes to be applicable by needle transfer dispensing to the slits and to flow into the slits forming the same proper setup as we have proven for larger cavities in deliverable 4.4. After the dispensing the subsequent solvent evaporation is challenging too since the greater ratio of the surface area of the slit side falls to electrode surface imposes special requirements to the membrane adhesion.
The sensor validation will be done in artificial ISF covering the full range of expected flow rates and range of concentrations of the ISF in the final application. Also testing of the most common interfering substances, such as acetaminophene and ascorbic acid, will be done.
The final sensor with the connector cannulas is shown below.
The sensor demonstrated in deliverable 4.4 could sense flows of down to 1 µl/hour, meaning in deliverable 4.5 we were able to reduce the measurable minimal flow by a factor of 20. It therefore can be stated that the goal of the deliverable was achieved.

In the course of the specification of the Central Data Warehouse (CDW) it became apparent that by simplifying access to data and by providing sample sets, development on tasks depending on this data can be parallelized. Also, in order to not only rely exclusively on field trials for data generation, a simulator for bio–signals has proven to be beneficial.

The Alpha system combines different sensing modules in a redundant configuration on both physical and data level. This platform has been conceived to allow the sharing within the consortium of a common vision on the SIXTHSENSE potentiality, on the base of a practical experience. Parts of the developed Alpha system will be integrated in the demonstrator that will allow laboratory and field testing.

The proposed system represents a solution in which the technological assets brought into the project by different partners has been integrated to evaluate in relevant conditions the soundness of preliminary approaches and the interplay of different modules, all in compliance with the common vision of SIXTHSENSE.
The platform described will allow the testing of each sensor or module. The Alpha prototype does not foresee the use of all sensors which are being developed in the project, but will focus on the set that is on a higher TRL and will allow field tests in the second year of the project. The sensors and modules on lower TRL will be tested in laboratory conditions, by using the same equipment (Alpha mobile device) but outside the presented functional prototype.

For this reason, a different solution was envisaged, the Beta version is based on an elastic stretchable garment, also if this solution can be perceived less performant in term of comfort and usability, as confirmed by the questionnaire results, collected during the Bormio trials, this functional version is considered as a mandatory step to validate the integration of the sensors and develop a comfortable vest for the Gamma platform. Design started with the materials selection, a very innovative elastic structure has been selected and different mock-ups have been realised to test functionality and material performances, as well as to assess wearing requirements during Bormio field trials. The first responders that participated in Bormio trials, have been considered as a focus group for the design process.
The garment is formed from 2 rectangular straps joined in the middle section to form a stretchable belt as shown in the figure below. The material used is stretchable in one direction, so that the garment can be stretched around the body, but the vertical dimension is stable. One side of the material is smooth, while the other is fuzzy, allowing it to work as the “loop” component of a hook-and-loop closing mechanism (velcro).
There is an orange line sawn down the middle of the garment, serving as a simple indicator for symmetrical positioning of the belt on the torso.
The following image shows the first BETA prototype with the indication of the position of the sensors and actuators.

The GAMMA version represents a streamlined version of the SIXTHENSE system focusing on usability and robustness, for effective use in relevant conditions of the environments where the first responders need to operate.
The sensors for ECG and temperature measurement are embedded in a fitted vest that adheres to the users body, while allowing full range of unhindered movements and being is simple to apply and remove. Segments that hold the electrotactile electrodes and multielectrode array of sensors for electrochemical sensing are especially designed to feature padding to ensure intimate connection with the user’s skin even in high intensity physical activity.
The first version of the gamma prototype has been piloted with mountain rescuers in the Kopaonik field trials in March 2023.

The main aim of this deliverable is to establish an initial engagement with SIXTHSENSE project stakeholders. Alpha prototype is presented to main stakeholders identified by the project partners with the aim to receive feedback and influence on the achieved technology development. The early-stage involvement of external partners will enhance the number of sectors where this innovative technology could be applied.
In this document, the main information related to the preparation and execution of Alpha stakeholders’ workshop is reported. The initially planned face to face event in a parallel session of a Conference was changed to an online workshop, with several talks and demonstration videos. The selected group of stakeholders were invited to participate in the workshop and smooth and effective communication pathways were established for the future. Main outcomes and feedback provided by the stakeholders are collected and will be considered for a better implementation of the SIXHTSENSE project and future stakeholders workshop.
The workshop was attended by representatives of TRAGSA, BFK, Aitex, Textil Santanderina and Motorola. Comments and feedback provided by stakeholders were obtained during the workshop and filled after the event in a form of a survey. Information collected has been divided depending on the topic discussed in three different sections.
1. Workshop organization and engagement with SIXTHSENSE project
All the entities found the workshop interesting or very interesting, information provided was comprehensive or very comprehensive, and all participants liked the reduced group of participant and showed their interest to keep updated about the evolution of the project and the next steps.
2. Sensing and electrotactile biofeedback technologies in alpha prototype
The monitoring of physical and chemical parameters was interesting for all the stakeholders. Electrotactile biofeedback technology was very well received and it was thoroughly dicussed. The positioning of the electrotactile biofeedback technology was preferred by stakeholders to be used as an armband or to be located in the vest. The potential of the central dashboard in cases when the team coordination is required was discussed, as it could be converted in the most added value component of the SIXTHSENSE technology.
3. Sectors and fields of applications
Beside the main use intended for first responders, the core technology of the SIXTHSENSE project is envisioned so that it can be later modified or adapted in some other sectors, and as reported by stakeholders, those can be: sports sector, workers 4.0 (petrochemical and heavy industries), healthcare (monitoring of long term and low movement patients) or space work programmes and aeronautical applications.
