Colloidal self-assembly of soft neural interfaces from injectable photovoltaic microdevices
Mahmut Selman Sakar, Zhangjun Huang, Murat Kaynak, Haiyan Jia
Biomimetic retinas with a wide field of view and high resolution are in demand for neuroprosthetics and robot vision. Conventional neural prostheses are manufactured outside the application area and implanted as a complete device using invasive surgery. He ...
2023Revealing the complexity of ultra-soft hydrogel re-swelling inside the brain
Stéphanie Lacour, John Martin Kolinski, Outman Akouissi, Olivier Didier Christian Rizzo, Michael Shur
The brain is an ultra-soft viscoelastic matrix. Sub-kPa hydrogels match the brain's mechanical properties but are challenging to manipulate in an implantable format. We propose a simple fabrication and processing sequence, consisting of de-hydration, patte ...
2023Toward higher-performance bionic limbs for wider clinical use
Most prosthetic limbs can autonomously move with dexterity, yet they are not perceived by the user as belonging to their own body. Robotic limbs can convey information about the environment with higher precision than biological limbs, but their actual perf ...
NATURE RESEARCH2021Virtual reality simulation of epiretinal stimulation highlights the relevance of the visual angle in prosthetic vision
Diego Ghezzi, Enrico Migliorini, Jacob Thomas Thorn
Objective. Retinal prostheses hold the potential to restore artificial vision in blind patients suffering from outer retinal dystrophies. The optimal number, density and coverage of the electrodes that a retinal prosthesis should have to provide adequate a ...
2020Soft And Wearable Transducers: Opportunities And Challenges For Daily Use
Soft bioelectronic interfaces are broadly defined as microfabricated devices, distributed over large-areas, and with mechanical properties suited to comply the soft and dynamic biological tissues. The hybrid integration and processing of materials ranging ...
IEEE2019Designing sensory feedback approaches for restoring touch and position feedback in upper limb amputees
Upper limb amputation disrupts most daily activities and reduces the quality of life of affected individuals. Building a suitable prosthetic limb, which can restore at least some of the lost capabilities, is a goal which has been pursued for centuries. In ...
EPFL2018A comprehensive study of neural retina stimulation towards better visual prosthesis resolution
Diego Ghezzi, Marta Jole Ildelfonsa Airaghi Leccardi, Laura Ferlauto, Naïg Aurelia Ludmilla Chenais
A major obstacle to make retinal prostheses a realistic technology to restore a functional form of vision allowing normal mobility is the low resolution achieved by current devices. Aims. Using photovoltaic pixels based on organic materials, we aimed at bu ...
2018Decoding bipedal locomotion from the rat sensorimotor cortex
Silvestro Micera, Grégoire Courtine, Rubia van den Brand, Jacopo Rigosa, Lucia Florinda Friedli Wittler
Objective. Decoding forelimb movements from the firing activity of cortical neurons has been interfaced with robotic and prosthetic systems to replace lost upper limb functions in humans. Despite the potential of this approach to improve locomotion and fac ...
Institute of Physics2015Stable Myoelectric Control of a Hand Prosthesis using Non-Linear Incremental Learning
Stable myoelectric control of hand prostheses remains an open problem. The only successful human–machine interface is surface electromyography, typically allowing control of a few degrees of freedom. Machine learning techniques may have the potential to re ...
2014Sensing Pressure Distribution on a Lower-Limb Exoskeleton Physical Human-Machine Interface
A sensory apparatus to monitor pressure distribution on the physical human-robot interface of lower-limb exoskeletons is presented. We propose a distributed measure of the interaction pressure over the whole contact area between the user and the machine as ...
