MANCHESTER, N.H.--()--Mobius Bionics LLC is pleased to announce the commercial introduction of the LUKE arm. The LUKE arm is the first prosthetic arm cleared by the US Food and Drug Administration (FDA) in the new product category for integrated prosthetic arms.

Developed by DEKA Research & Development Corp. (DEKA), the LUKE arm incorporates the latest technology in electronics, motors, batteries, and materials. The arm offers state-of-the-art flexibility, strength, and dexterity to provide greater independence for people with forearm through shoulder-level amputations. “[This arm’s] functionality far surpasses anything that I’ve had so far,” said a participant who used the arm in DEKA’s clinical study. Mobius Bionics is now accepting names of people interested in owning one of the first LUKE arms.

Unmatched by current devices, the LUKE arm is an advanced prosthesis with many innovative features that give amputees the capability they deserve, including:

  • A powered shoulder with the capability to reach overhead or behind the back
  • A powered elbow with the strength to lift a bag of groceries from floor to tabletop
  • A powered, multi-movement wrist with the precision, range of motion, and dexterity to hold a glass of water overhead or at waist level without spilling
  • A hand with four independent motors and a conforming grip to hold everything from delicate items such as a phone or an egg to heavy items such as a gallon of milk without worrying that the item will slip or break
  • An innovative grip-force sensor that senses how firmly something is being grasped and communicates that information to the user
  • A variety of ways to control the arm, including electromyographic (EMG) electrodes and foot-mounted inertial measurement sensors
  • Protection against water and dust – offering peace of mind when used inside and outside the home.

All of these features and capabilities are provided to the prosthetist as a complete system, eliminating any potential compatibility issues between joints or components.

The LUKE arm is the result of years of research and testing by nearly 100 amputees for over 10,000 hours of use. Mobius Bionics is excited to be able to bring this innovative technology from the research lab to amputees everywhere. “Up to this point, design in prosthetic arms has been limited to incremental changes. We developed the LUKE arm to change the game for amputees – creating an innovative, integrated system that offers greater functionality and independence to our wounded warriors and other amputees,” explained Dean Kamen, President of DEKA.

Mobius Bionics has chosen Universal Instruments Corporation (Binghamton, NY) to serve as the contract manufacturer for the LUKE arm. Mobius Bionics is leveraging Universal Instruments’ decades of experience manufacturing precision electromechanical solutions to produce the arm. “Universal Instruments is pleased to partner with Mobius Bionics to bring the LUKE arm to market, enabling greater independence for upper limb amputees,” said Keith O’Leary, CFO & COO of Universal Instruments.

Mobius Bionics is preparing the arm for launch in late 2016. Contact Mobius Bionics to join the growing list of people interested in owning a LUKE arm by calling 855-MOBIUS-1 (855-662-4871) or visiting

History of the LUKE Arm - Revolutionizing Upper-Limb Prosthetics

The LUKE arm was developed by DEKA Research & Development Corp. as part of the Defense Advanced Research Projects Agency’s (DARPA) Revolutionizing Prosthetics program with additional funding from the U.S. Army Medical Research and Materiel Command through a contract with the Army Research Office. Launched in 2006, DARPA’s program began with a radical goal: develop an advanced electromechanical prosthetic upper limb with near natural control that would dramatically enhance independence and improve quality of life for amputees.

Working with DARPA and the Department of Veterans Affairs (VA) Rehabilitation Research and Development Service under a federal interagency agreement, DEKA spent years directly engaged with amputees in a number of studies, including VA studies, to better understand how the intersection of biology and engineering could ultimately lead to advanced prosthetic technologies. DEKA obtained performance feedback on the design from VA clinical optimization and take-home studies and DEKA take-home studies. “Working one-on-one with the amputees and learning what they liked and didn’t like about using prostheses proved invaluable to our product development process. Thanks to their insight and input, we have been able to construct the most advanced FDA-cleared design that the world of upper-limb prosthetics has seen to date,” noted Kamen.

DEKA’s efforts on the Revolutionizing Prosthetics program resulted in the LUKE arm being the first advanced, integrated prosthetic arm cleared by the FDA. The LUKE arm has many features that offer greater functionality and independence to amputees, such as

  • Up to 10 powered degrees of freedom
  • Available in different configurations to serve amputees from transradial to shoulder disarticulation
  • Grip-force feedback
  • Resistance against water and dust
  • Innovative, new inertial measurement sensors worn on the feet as an option to control the arm

Since the inception of the Revolutionizing Prosthetics program, DARPA has supported efforts to bring this advanced technology to market with the objective that Service members with arm loss would regain the independence and capability that they lost. DARPA’s most recent support provides resources to assist in establishing Mobius Bionics so that the arm can be provided to amputees, particularly to veterans.
