At the COMPAMED 2024 exhibition, Q.ANT debuted its photonic quantum magnetic field sensor, an advanced biosensor designed to enable mind-controlled prosthetics. This sensor detects minuscule electrical and magnetic signals, translating them into commands that control prosthetic limbs. In collaboration with Fraunhofer IPA, Q.ANT’s innovation opens the door for prosthetic users to control artificial limbs with unprecedented precision. This advancement demonstrates the possibilities of quantum technology in bridging the gap between biological signals and machine control, potentially enhancing life quality for individuals reliant on prosthetics.
This research aims to create advanced control systems for prosthetic limbs that replicate natural human movement with precision. Controlling current prosthetics effectively remains a challenge due to the complexity of neuromuscular signals. By first decoding signals from muscle fibers, where each neuron controls many fibers for clearer patterns, researchers are working towards interfaces that will eventually connect with neurons at the spinal cord and brain levels. This gradual approach paves the way for prosthetics with highly refined, natural-like control.
“Starting with broad muscular activation similar to current EMG technology, the plan is to develop increasingly sensitive sensors to capture subtle neuromuscular signals with precision. These advancements will lead to high-density systems that outperform existing technologies, ultimately enabling neurography by detecting individual neuron connections to muscles, neurons, or brain sensors, and eventually progressing to spinal cord-level control,” Dr. Leonardo Gizzi, Head of Research Team at Fraunhofer IPA, said in an interview with MedicalExpo e-Magazine.
