This always bears a big risk of infections as the skin is the #1 protection from bacteria. Even prosthetics fully under the skin have this risk, and septic shock is a possibly lethal threat. And we humans love to put our hands to various sometimes more, sometimes less, dirty places.</text><parent_chain></parent_chain></comment><story><title>The first dexterous and sentient hand prosthesis has been successfully implanted</title><url>http://www.detop-project.eu/news/the-first-dexterous-and-sentient-hand-prosthesis-has-been-successfully-implanted/</url></story>

They&amp;#x27;re actually sending signals directly through the percutaneous bone anchors, which is pretty rad in my book. Looks like the hand just snaps on to the anchors and you&amp;#x27;re ready to go, albeit with years of retraining the nerve endings for the new signals.</text><parent_chain></parent_chain></comment><story><title>The first dexterous and sentient hand prosthesis has been successfully implanted</title><url>http://www.detop-project.eu/news/the-first-dexterous-and-sentient-hand-prosthesis-has-been-successfully-implanted/</url></story>
