About Fasikl

Fasikl is a neuro-AI company that develops advanced AI-supported neural platforms and therapeutics for neurological conditions. Spun out of the University of Minnesota in 2019, Fasikl leverages over two decades of neural engineering research to create innovative treatments that interact directly with the human brain and nervous system. Their approach focuses on human-AI co-adaptation, where biological and artificial intelligence work together to provide personalized and adaptive therapies.

Fasikl’s flagship product, the Felix NeuroAI Wristband, is the first FDA-cleared, noninvasive AI therapeutic device specifically designed for essential tremor. This prescription-only device delivers electrical stimulation to nerves at the wrist to modulate neural activity, offering all-day tremor relief without the need for drugs or surgery. Clinical trials have demonstrated that the Felix NeuroAI Wristband significantly improves daily function and quality of life for individuals with essential tremor. Additionally, Fasikl is developing the Fasikl-X Nerve-Computer Interface (NCI) System, an investigational implantable peripheral nerve-computer interface that has received FDA Breakthrough Device designation. This technology aims to enable amputees and paralyzed patients to intuitively control prosthetic limbs or computers and to alleviate post-amputation pain by capturing and interpreting neural signals at a high resolution.
