Mercedes' response? They made him the most advanced prosthetic hand in the world.Mercedes worked with Touch Bionics to customize an i-LIMB Pulse hand for Matthew, who was born without a hand. The i-LIMB is a bluetooth-enabled prosthesis that allows wearers to tie shoes, put on belts, and use a pen to write or draw.
