earlier prototype of the arm, the Proto 1, was shown in April of this year, and now the team of scientists is scrambling to ready the arm's second iteration, the Proto 2, in time to show it off this week at the 25th Darpa Systems and Technology Symposium (where it will likely be joined by Dean Kamen's Darpa funded bionic arm). Researchers hope that the prothesis, which is currently controlled by skin-surface-attached myoelectric sensors, can be made more intuitive by adding injectable sensors, which send increased amounts of signals (and have improved clarity) allowing for greater control of the arm. In time, the team hopes to move to nerve-attached electrodes, or electrode arrays implanted on the brain, which will eventually allow for full user dexterity.
