Imagine trying to draw a detailed picture using only a few thick markers; that is how current brain implants work. This project creates a way to 'trick' the brain into seeing much finer detail by using clever electrical patterns instead of just adding more wires. It is like upgrading a low-resolution screen to high-definition without needing a massive increase in hardware.
Current visual prostheses have too few electrodes to provide useful sight, and adding more electrodes creates physical and biological risks in the brain.
Thin, flexible electrode arrays and a computational model of the monkey visual cortex to optimize stimulation patterns.
If you are a manufacturer dealing with the physical limits of how many wires can fit in a brain — this project developed stimulation protocols that increase visual resolution by 20 times the number of physical electrodes. This allows for clearer vision without needing impossibly large implants.
If you are an R&D firm dealing with poor signal selectivity in cortical implants — this project developed thin, flexible electrode arrays and current steering techniques. This ensures better biocompatibility and more precise neural activation patterns.
If you are a software developer dealing with the difficulty of translating images into brain signals — this project developed a computational model of the monkey visual cortex. This allows for the simulation and optimization of stimulation patterns before human implantation.
Based on available project data, there is no information regarding the unit cost or commercial pricing of the developed electrodes and protocols.
The project has successfully fabricated thin, flexible electrode arrays, but based on available project data, industrial mass-production capacity has not yet been detailed.
Based on available project data, specific patent numbers or licensing terms are not provided, though the project involves a consortium of universities and an SME.
The project demonstrated recordings of neural activity in nonhuman primates for periods up to 2.5 years.
The technology focuses on using sophisticated stimulation protocols and flexible arrays to achieve 20X the resolution of the physical electrode count.
The consortium is research-heavy, consisting of 5 partners across 3 countries (BE, ES, HU). With 2 universities, 1 research organization, and 1 SME, the industry ratio is 20%. This structure suggests the project is currently in the high-tech validation phase, leveraging academic expertise in neurobiology and imaging to feed into a single industrial partner for future commercialization.
