Sensing and grasping as if it was a real hand: In this video nine years after his hand was amputated Dennis Aabo Sørensen obtains a biomechatronical hand – the LifeHand 2. Prof. Dr. Thomas Stieglitz and his team from the department of microsystem engineering (IMTEK) as well as researchers of five additional institutions made this possible.
Electrodes were surgically inserted in Dennis’ upper arm. The researchers at IMTEK at the University of Freiburg developed the electrodes that were attached to the peripheral nerves during this operation. By means of this interface Dennis receives Information about form and texture of objects that he wants to grasp. This enables Dennis to feel objects and to grasp them precisely by applying the correct force. In this clip Dennis and researchers report on the operation and how they tested the new hand.
