Overview
Paradromics is developing a high-bandwidth, implantable brain-computer interface specifically designed to restore natural speech communication to people with paralysis or locked-in syndrome. The company's Connexus Direct Data Interface uses a dense array of microwire electrodes capable of recording from thousands of neurons simultaneously, combined with a custom ASIC that achieves data transmission rates far exceeding existing BCI platforms. The system targets the speech motor cortex to decode intended speech directly from neural activity, with a goal of enabling 40+ words per minute communication. The primary patient population is individuals with ALS, brainstem stroke, or high-level spinal cord injury who have lost the ability to speak. Paradromics received DARPA funding through the Neural Engineering System Design (NESD) program, which set the technical benchmark of 1 million neural recording channels at a bandwidth of 1 Gbps — targets that shaped the company's technology roadmap. The device is intended to work as a fully wireless, implantable data bridge between the cortex and external devices. Paradromics differentiates through its focus on communication bandwidth as a first-class engineering objective, rather than treating it as secondary to electrode count or surgical profile. The company's microwire bundle approach allows scaling to very high channel counts with minimal tissue displacement, and the custom silicon handles signal processing at the implant to reduce wireless transmission load. Paradromics is backed by DARPA and private investors and is advancing toward first-in-human clinical studies.
