Imagine a world where every patient could regularly receive preventative scans of their brains. What sounds great in theory has always been a logistical problem so far. The entire MRI capacity of the United States is insufficient for regular preventative scans for dementia, let alone any other conditions. Kernel has set out to address this issue.
Kernel’s neuroimaging headset, Kernel Flow, collects high-resolution data at the scale required for medicine. Kernel Flow scans are limited to the cortex, the evolved part of the brain where most cognitive capabilities are encoded.
By accepting a few trade-offs, Kernel is working to enable medical professionals to leverage the portability and ease of use of Kernel Flow. This makes all the difference for patients who already struggle to visit a clinic or go through an MRI scan. To guarantee comfort and medically accurate scans, Kernel had to find the sweet spot between high-performance and power consumption, and ST’s foundry services helped them find the optimal balance.

When we set out to build a non-invasive and optical-based neuroimaging system, we didn’t know if our vision was even possible. Through a rigorous technology exploration, we found that ST’s Imaging Foundry had a technology node that made all of the difference

When Kernel started, back in 2016, nobody thought about having their brain measured unless they had a medical condition. The landscape was split among very invasive technologies without any practical uses for the wider population and robust medical technologies with high operational costs.
Kernel saw an opportunity between these extremes, but to appeal to consumers, they first had to demonstrate the near-medical accuracy that would place the Flow in the league of fMRI (functional MRI) and EEG (electroencephalogram).
Thanks to time-domain near-infrared spectroscopy (NIR), they were able to offer neuroimaging at levels comparable to clinical solutions, but still flexible enough to use it where the patients are already receiving care. However, getting there posed some challenges. Kernel’s first design included 312 sensors, each of which used more than 100 milliwatts.

The MPW program significantly reduced risks and costs, underscoring ST’s pivotal role as a tech enabler in Kernel’s groundbreaking innovation.

To mitigate these challenges, Kernel partnered with ST, leveraging their cutting-edge process node and the Multi-Project Wafer (MPW) program. ST’s collaboration empowered Kernel to embed robust computational power and custom algorithms into each sensor, efficiently reducing data rates. This transformation not only minimized the Flow’s reliance on external power but also improved comfort for the patients. Thanks to ST’s technology, Kernel successfully decreased data bandwidth requirements by 1,000,000 time and streamlined both data compression and encryption in a single step.
As Kernel continues its partnership with ST, they continue to explore more power-saving options. It’s only a matter of time before the Flow becomes the new norm in practices everywhere.
