Soft Implantable Electrodes to Interface with the Brain

Neural implants aim at restoring lost or impaired functions of the nervous system by electrical stimulation or recording of the brain. Current neural implants suffer from a mechanical mismatch compared to the soft host tissue, as they constrain mechanically the physiological motion of the central nervous system. This mismatch causes poor electrode-tissue contact, leading to unspecific stimulation or recording, as well as chronic scarring. At Neurosoft Bioelectronics, we overcome these fundamental limitations by developing soft neural electrodes, using more compliant materials, that seamlessly interface with the brain, promoting the long-term bio-integration of the devices and reducing surgical risks.
