Brain-computer interface technology development

The brain-computer interface (BCI) sector is seeing significant capital investment directed toward both implantable hardware and specialized semiconductor components.

In late September 2026, Precision Neuroscience secured $250 million in Series D funding, bringing its total investment to $430 million. The company utilizes its ‘Layer 7’ technology, a thin-film device with 1,024 electrodes that sits on the brain surface to mitigate infection and scarring risks. Following FDA clearance for short-term use in April 2025, the company is now working toward approval for permanent wireless implants.

By October 2026, MintNeuro, a spinout from Imperial College London, raised $5 million to scale its semiconductor platform. Unlike direct interface developers, MintNeuro focuses on modular chip architectures designed for neural sensing, signal processing, and stimulation. The company has established integration milestones with partners like Motif Neurotech and Amber Therapeutics, aiming to provide specialized components for medical implants and wearable neurotechnology.
