The Biohand, a new intelligent bionic hand, integrates bionics, mechatronics, materials science, biomedical engineering, and information technology. It is equipped with self-developed somatosensory control technology, making the bionic hand as flexible as a human hand. It features six internal actuating units, ensuring that each finger can move independently, with the thumb capable of moving in two directions, truly simulating the natural movements of a human hand.
