After launching its world-beating i-LIMB prosthetic hand last year, Touch Bionics is taking things in a different direction with feeling some competition from the "Fluidhand." The new hand uses miniature hydraulics to flex the fingers, and can better interact with objects -- like grasping things with irregular surfaces -- than the five motor i-LIMB. Fludihand is also designed to have a more natural feel than previous prosthetics, and gives feedback to the stump to let the user sense the strength of the grip. Currently Fluidhand is just in the prototype stage, with one patient so far testing both prosthetics against each other in a battle to the death.

Update: Sorry for the confusion, Fluidhand was built by a some researchers in Karlsruhe, Germany, not by Touch Bionics.
