BrainCo unveils bionic hand that turns neural and muscle signals into finger control

China's BrainCo has introduced a bionic prosthetic hand that reads muscle and nerve activity through a skin-worn cuff, with no implants required. It weighs 383 grams, delivers over 50N of grip force, has about 0.38s latency and positioning accuracy down to a tenth of a degree.

• Prosthesis weighs 383 grams with over 50N grip force
• About 0.38s latency and 0.1-degree positioning accuracy
• Skin-cuff sensors, no surgical implants needed
• Takes about a minute to put on, charges via USB-C
