On May 14, 2025, a groundbreaking milestone was achieved in neuroscience and neurotechnology. A research team from the University of Michigan successfully tested Paradromics’ Connexus device, a fully implantable brain-computer interface (BCI), on a human patient — marking the first-ever instance of wireless brain signal recording in a person.
The test was conducted during an epilepsy surgery, where the Connexus device was temporarily implanted in the patient’s temporal lobe. This allowed researchers to evaluate the device’s ability to detect and transmit neural signals accurately.
What makes the Connexus device truly revolutionary is its compact design and advanced capabilities. It features a dense array of 421 microelectrodes, enabling it to capture precise electrical activity directly from individual neurons. These neural signals are then transmitted wirelessly to an external computer, where AI-powered algorithms interpret them into meaningful outputs — such as synthetic speech or movement commands.
This advancement could be a game-changer for individuals living with neurological disorders like paralysis or speech impairments. By enabling communication between the brain and external devices, the Connexus device holds the promise of restoring lost abilities and dramatically improving quality of life.
Paradromics is now gearing up for a year-long clinical trial to further evaluate the safety, reliability, and real-world impact of the Connexus device on patients. If successful, this technology could pave the way for a new era of brain-computer communication.
