About the
Technology

  • ENRICH is designed mimicking the functionality and controllability of human hand.
  • The real-time EMG based controller enables ENRICH to perform grasping operations in 250.80 ± 1.1 milliseconds, comparable to the time required by human hands i.e., 300 milliseconds.
  • Fastest prosthetic hand satisfying human hand neuromuscular constraint
  • Multiarticulate hand mimicking human hand
  • Single channel EMG controlled prosthetic with less learning time
  • Anthropomorphic and ergonomic design with powerful grasp
  • Lightweight
  • Adjustable sockets
