Scientists have integrated a massive array of small sensors to read the intricate interference of electrical signals and predict the sounds individuals are trying to produce.

This technology opens the door to empower those facing difficulties in speaking due to neurological communication disorders through thought. The sensors detect the muscles intended to move in the lips, tongue, jaw, and throat.

According to Dr. Gregory Koehn from Duke University, this development is crucial for patients with debilitating motor disorders such as Amyotrophic Lateral Sclerosis (ALS) or Locked-in Syndrome, as these conditions can affect their ability to speak. Jonathan Viventi, a biomedical engineer at Duke University, explained that this technology is still in its early stages. Despite the slow pace compared to natural speech, one can envision the potential direction this technology might take in the future.

The array of electrical electrodes was built on an ultra-thin, medically graded flexible plastic, with electrodes spaced less than 2 mm apart, allowing it to detect precise signals even from nerve cells very close to each other.

Dr. Koehn stated that they are working on developing a similar type of wireless recording devices to enable greater movement and enhance mobility, increasing the flexibility of using this technology.
