Promising New Developments in AI Prostheses Raise Stark Questions

The Olympic performance of amputee runner Oscar Pistorius in 2012 led to accusations that the prostheses performed better than natural limbs

Our rapidly developing ability to interface neurons and electronics offers amputees much more functional prostheses (though it is still a long and winding road). Here are some encouraging recent developments: ● A newer technology pioneered at Helsinki University Hospital and Imperial College London enables improved compatibility between a prosthesis and the remaining portion of the amputee’s limb. One current problem is that the connections between the prosthesis and the muscle that gives the commands (the myoelectric interface) can grow weaker due to external factors like sweating. Currently existing systems require adjustments or other measures from the user, but Yeung and his team developed a fully automated system that learns during normal use and thus adapts to varying conditions. “In this…
