Jacob Hyatt trialing his high-tech bionic arm. See SWNS story SWTPbionic. A little superhero fanboy who was born with one hand missing is hoping to get £13k from kind donors so he can have a high-tech bionic arm - just like Iron Man. Seven-year-old Jacob Hyatt was born with his left hand missing and had the opportunity to trial a bionic arm earlier this year. He quickly became desperate to get one of his own and mum Bernice Hyatt, 33, is hoping donations from the public will be enough to get her son one. The state-of-the-art 'superhero arm' designed by Open Bionics costs £13,000.
