➀ Quantum sensors are being developed to register nerve impulses without contact, offering new possibilities for prosthetics. ➁ Researchers at Fraunhofer IPA are working with Q.ANT to create a prototype of a prosthetic arm controlled by neural commands like healthy limbs. ➂ The technology, which uses a diamond-based sensor, promises non-contact and robust measurement of human biosignals, potentially revolutionizing the field of prosthetics.
