The Nexus hand prosthesis combines a modular design with advanced functionality, technology, and remote programming support to provide an unrivaled user experience with a powerful level of customizable refinement. This prosthetic hand provides intuitive and robust grip patterns and ways to switch between them. Its grip-mapping capabilities allow the user and clinician to input custom-made gesturing into the device to adjust the thresholds, amplifying weaker signals so that the hand still operates at full speed. Through the companion app and web portal, the technical team can distribute updates instantaneously to any user globally.
