These arms are modelled on the» Belgrade Hand», one of the first artificial hands created with a sense of touch invented in 1963 by the Serbian scientist Rajko Tomović at the University of Belgrade responding to the limb loss of soldiers in the aftermath of the Second World War. (henry-moore.org)
Inadequate tactile feedback is a leading shortcoming of prosthetic limbs, but for artificial hands, just a few sensors that relay grasp pressure back to the user can provide the functionality needed to enable delicate tasks (2). (science.sciencemag.org)
Weir has developed such a device, called an Implantable Myoelectric Sensor, or IMES, which he has been using to develop artificial hands. (discovermagazine.com)
