Chinese researchers have developed a brain-computer interface (BCI) called SpiralE that connects people’s brains to a computer via the inner ear. Unlike other BCIs, SpiralE doesn’t require invasive surgery and can be used daily. The flexible in-ear material creates a digital connection to the brain, potentially enabling applications like thought-to-text translation and human memory augmentation. While BCIs hold promising potential, they also raise ethical concerns related to privacy and human rights. The research was published in the scientific journal Nature Communications and demonstrates the possibility of integrating wearable electronics into real-life applications.
