Starfish Neuroscience, a startup co-founded by Valve CEO Gabe Newell, has published an article revealing the first details of its brain-computer interface (BCI) chip.
The firm proposes a “new class of minimally-invasive, distributed neural interfaces that enable simultaneous access to multiple brain regions.” Moreover, a Starfish BCI could be the first fully wireless, battery-free implant available, if all goes to plan. According to its blog, the startup’s first chips are expected to arrive “in late 2025.” Perhaps the relationship with Newell means related tech will eventually find its way into gaming headsets and controllers.
In its report on the Starfish BCI news, The Verge notes that Newell’s fascination with BCIs began over 10 years ago, and that Valve once considered adding earlobe monitors to its VR headset products. As recently as 2019, Valve also publicly explored BCIs for gaming. Later the same year, Newell incorporated Starfish Neuroscience, and we are now seeing the first fruits as it emerges from stealth.
In its new blog post, Starfish says its BCI has the opportunity to do well thanks to two key features, its minimal size and the eschewing of built-in battery power. In regular use, the Starfish processor will consume just 1.1mW, it says. That contrasts with the Neuralink N1, which uses around 6mW.
- Low power: 1.1 mW total power consumption during normal recording
- Physically small: 2 x 4mm (0.3mm pitch BGA)
- Capable of both recording (spikes and LFP) & stimulation (biphasic pulses)
- 32 electrode sites, 16 simultaneous recording channels at 18.75kHz
- 1 current source for stimulating on arbitrary pairs of electrodes
- Onboard impedance monitoring and stim voltage transient measurement
- Digital onboard data processing and spike detection allows the device to operate via low-bandwidth wireless interfaces.
- Fabricated in TSMC 55nm process
The startup also thinks that its smaller, lower power BCI implant(s) may work best connected to multiple parts of the brain simultaneously. For use in medical therapy, this multi-zone methodology could address human brain issues which affect several areas of the brain, like Parkinson’s disease.
Starfish isn’t so bold as to think it can go it alone with its new processor and BCI system. Rather, its blog floats the idea of collaborators on wireless power delivery and communication, and on custom implanted neural interfaces. It also admits “there is tons of work yet to be done here,” and is looking for employees, as well as partners, to boost its fortunes.
