German quantum technology company Q.ANT has developed a breakthrough quantum magnetic field sensor that can control prostheses, exoskeletons, and avatars using neural signals. The sensor’s precision allows it to measure fine electrical currents through their magnetic fields, providing native and intuitive access to biosignals. It can control prosthetic limbs via muscle signals, bringing significant advancements to medical technology. The sensor, with a compact design similar to a sunglass case, is highly sensitive and suitable for everyday use, making it accessible for various industrial applications such as quality assurance of hard disks and fault detection in power chips or batteries.

Q.ANT’s magnetic field sensor can operate at room temperature and offers reliable performance even under everyday conditions. It can measure the smallest magnetic fields in the picotesla range, enabling new levels of precision in prosthesis control, rehabilitation, and telemedicine. The magnetic sensor detects the small signals emanating from human muscles and transmits them to the prosthesis for appropriate action. This new technology improves the quality of life for people with arm or leg amputations and contributes to better social integration.

For additional information, you can visit the Q.ANT webpage for the magnetic sensor and access a product brochure for the sensor. A press release announcing this application of their sensor and Q.ANT’s upcoming demonstration at the Hannover Messe (April 22-26, Hall 2, Booth A31) can be found here.
