Control of Prostheses

Problem

Current myoelectric sensors, which are used to control prostheses, face limitations in accessing muscle signals. Specifically, they have difficulty accessing the subtle magnetic signals of muscle contractions, particularly from deeper muscle layers. This limitation in signal access can hinder the ability to achieve refined and natural control of prosthetic devices

Solution

Magnetic-field quantum sensors offer an alternative approach. They employ a non-invasive measuring method that can detect the subtle magnetic signals of muscle contractions. Crucially, these sensors have the potential to access signals not only from the upper muscle layers but also from deeper layers. This capability goes beyond the limitations of current myoelectric sensors. Looking to the future, there is also an aim to develop brain-computer interfaces (BCIs) that would interpret brain-generated magnetic fields using this technology.

Impact

By providing access to subtle and deep muscle signals, these quantum sensors have the potential to pave the way for a more refined, natural control of prostheses. As the technology advances towards interpreting brain signals through BCIs, it could offer unprecedented control over prosthetic devices.
