Signal Consumer earbuds patented as biosignal sensors

Summary

This signal is a patent from Apple for technology that can measure biological signals, such as brainwaves, through the ear using AirPods. Sitra cites the patent filing on a biosignal sensing device using dynamic selection of electrodes, dated July 2023. The approach would put neural sensing inside a mass-market accessory that many people already wear daily. It shows how brain measurement could reach consumers without any dedicated medical device. The signal also raises privacy questions about who collects and uses such data. Sitra places it among the signals behind an imagined future article where neurotechnology has become commonplace.
