3. Sørensen tested the hand over a four-week clinical trial.
The hand has several sensors attached to each tendon of each finger. Each sensor measures the amount of force Sørensen uses to grasp each object. This information is relayed to electrodes implanted in Sørensen’s nerves and allows him to “feel” the object in real-time.
“For the first time we were able to restore real time sensory feeling in am amputee while he was controlling this sensorised hand,” said Silvestro Micera, a researcher at EPFL Switzerland.
