Elbows

Externally powered elbow with myoelectric control, 6 kg active lift, and free-swing mode.

Materials & Highlights

Carbon fiber shell

The PowerHinge E2 restores active elbow flexion to transhumeral users through proportional myoelectric control — stronger muscle signal, faster motion — with an active lift capacity of 6 kg and a locked static hold of 23 kg. A flick-gesture free-swing mode lets the arm swing naturally during walking, then re-engages power the moment a signal returns.

A brushless gearmotor drives a harmonic reduction stage for quiet operation under 52 dB, powered by a swappable li-ion cell good for a full active day. The forearm is carbon-shelled with internal cabling channels for hand and wrist wiring; total weight 880 g with battery, flexion 4 to 145 degrees.
