Apple acquired Sonera Magnetics, a California startup that develops non‑invasive magnetic sensors intended to pick up neural and muscular signals for wearables and gesture control.
The deal Sonera's magnetic‑sensor hardware and signal‑processing expertise into Apple's device and health workstreams, reporting by The Verge first revealed.
Sonera had described its aim as making "brain activity as easy to measure as heart rate, temperature, and other physiological signals," a 2023 claim that frames why Apple sees the technology as relevant to future Apple Watch health features and gesture controls for devices such as Vision Pro.
Public sources characterise Sonera's kit as non‑contact magnetic sensors for brain and muscle monitoring and say the startup's work aligns with accessibility and assistive‑control use cases Apple has explored non-invasive brain and muscle sensors.
