Stroke is one of the leading causes of long-term disability, with roughly two-thirds of survivors experiencing significant impairments in their hands and arms. While some people eventually regain that function, many live with persistent paralysis or weakness. Epia Neuro, a newly launched startup out of San Francisco, wants to help more stroke patients regain hand function with a brain implant and motorized glove. It’s among a growing number of companies developing brain-computer interfaces , devices that read neural signals from the brain and translate them into specific actions. The space has seen a huge influx of investment in recent years, with Elon Musk’s Neuralink raising $500 million last year and Sam Altman’s Merge Labs emerging from stealth in January with $252 million in funding. Neuralink and others are building devices that give people with severe motor disabilities the ability to control a computer or speak with a digital voice. Epia’s technology aims to help people move their own hands again.…
