Company Profile
Gbrain develops brain computer interface and neuromodulation systems using flexible cortical electrodes. Its core technologies, Phin Stim and Phin Array, aim to restore neural function and improve mobility in patients with neurological disorders such as Parkinson's disease and stroke.
Company Competitiveness
-
Ultra-thin Flexible Cortical Electrode : Gbrain's ultra-thin and flexible cortical electrode conforms to the brain’s surface, providing stable implantation and high-quality neural recording and stimulation.
-
Intellectual Property and Research : The company holds patents on flexible cortical electrodes and wireless neural interface, supported by peer-reviewed studies demonstrating technological excellence.
-
Clinical Collaboration Network : Partnerships with hospitals and research institutes establish a solid foundation for future clinical validation and global commercialization.
Key Product
Phin Array
-
Phin Array is an ultra-thin and flexible cortical electrode that conforms to the brain’s surface. It provides high-resolution neural recording and localized stimulation with minimal invasiveness. The design ensures stable long-term implantation and high signal fidelity for clinical and research use.
Phin Stim
-
Phin Stim is a fully implantable wireless neurostimulation device integrating Phin Array with a packaged chip set. It delivers targeted cortical stimulation through real-time neural feedback. 2.4 GHz Bluetooth communication and wireless charging system eliminate lead to stimulator wiring, reducing surgical complexity and hardware related risks.
