Periodic Reporting for period 2 - NerveRepack (Intelligent neural system for bidirectional connection with exoprostheses and exoskeletons)

Periodo di rendicontazione: 2024-06-01 al 2025-05-31

Sintesi del contesto e degli obiettivi generali del progetto

The main goal of the project is to develop a new generation of bidirectional implantable electrodes connecting the human nervous system with external mechatronic aid devices such as exoskeletons and exoprostheses, thus helping people with arm amputations or leg paralysis regain their motor and sensorial functions.
Electrodes will be the primary bidirectional interface to the nerves, followed by the implantable module, comprising an ASIC for signal processing, a microcontroller, an antenna for radio communication, a coil for wireless power charging and a supercapacitor for energy storage. To enable data communication to the mechatronic structures, as well as their power management and control (via AI modules) an embedded system will be designed, fabricated, and tested. This system will then be integrated into the mechatronic structures of exoprosthesis or exoskeletons. Due to the presence of bidirectional implantable electrodes a close loop between the user’s brain and the device’s control system will be created, with the AI module being used to learn and interpret the user’s synaptic signals.
All the components and modules will be designed, fabricated, and tested with demonstration being assured by integrating the neural implantable systems with exoprostheses and exoskeletons into three demonstrators aimed at different categories of patients: with forearm amputation, with lower limbs paralysis and with single leg paralysis. A new generation of exoprostheses and exoskeletons controlled by the patient’s brain via the nervous system will change the paradigm of support for people with disabilities and will have an important social, economic, medical, and technological impact. The technology advances including miniaturization, wireless communication and power supply, progresses in medical microsurgery tools and methods, new biocompatible materials and technologies will considerably contribute to the project implementation.

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

In the first year of the project, the partners within the consortium started implementing the activities from the project implementation plan that correspond to this period:
- The medical, functional and technical specifications were developed for all the devices that will be made within the project: the implantable systems (electrodes and the electronic module) for the two door cases, the mechatronic structure of the exoprosthesis, the mechatronic structures of the exoskeletons, power management/ wireless transfer system.
- The patient with forearm amputation who will use the exoprosthesis was also selected and the creation of the reserve list with patients with forearm amputation began.
- The general architecture of the implantable system was created (electrodes, connectors and electronic module)
- The implantable electrodes were designed for the two use cases.
- Innovative biomaterials for electrodes were tested.
In the current period, there were deliverables scheduled that contribute to achieving Objective 8: Biocompatibility study of new materials and devices used in implantable modules.
The selected biomaterials were forwarded to Ł-ŁIT, whose aim was to perform it from a biological perspective. In WP7, research methods were developed and in the Cell Laboratory, in accordance with the procedure, cytotoxicity on the HaCat-keratinocytes cell line was assessed.
D7.1 – Biocompatibility of component material) was scheduled for the end of March 2024.
Cytotoxicity analysis were done as part of biocompatibility assessment (cytotoxicity, hemocompatibility, gene alteration, carcinogenicity).

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

The general principles of promoting the essence of the project are carried out on a large scale, taking into account several dozen units from the consortium from over 10 European countries. Scala is the project website. The website has a fresh and dynamic look, based on the already established visual identification of the project: logo and colors.
NerveRepack will establish partnerships with institutional actors from several areas of interest (universities, think tanks, NGOs) and from other regions to discover potential and smart ideas. The plan is to reach out to the scientific ecosystem, through the organization of seminars, workshops on social media and networking opportunities for professionals from all fields in which the project is involved (e.g. doctors, sensor and intelligent systems engineers).
Promotional channels will allow knowledge and project results to pass from the scientific ecosystem to business market.
Overall, the proposed communication actions will get the project closer to the general public and will make the science associated with NerveRepack look appealing and exciting to them, as a breakthrough in improving life quality.
