The study, published in Nature, introduced a three-dimensional optical fibre gripper that can manipulate opaque particles, irregular micromechanical components and diverse single-cell types. By controlling light input, the microgripper can open, close and adjust its gripping force. Experiments showed it can generate forces more than 100,000 times greater than conventional optical tweezers, enabling high-precision manipulation, microstructure assembly and microscale sampling.
A patient suffering from tetraplegia steered a smart wheelchair through the neighbourhood with only his thoughts and directed a robotic dog to fetch a food delivery. These scenes were achieved during a recent clinical trial of a brain-computer interface conducted by a team from the Chinese Academy of Sciences (CAS).
This shattered the conventional boundaries of rehabilitation, carrying the brain’s command from a two-dimensional cursor on a screen into full-bodied, three-dimensional interaction with the physical world.
Brain-computer interfaces are designed to create a direct communication channel between the brain and external devices. Around the world, research groups have already demonstrated the laboratory feats, including “mind typing” and robotic-arm control. The enduring challenge is to make those systems reliable enough to vanish into a patient’s daily life.
