According to the article, ultrasound can measure brain activity and it can influence brain activity in deeper regions of the brain without invasive probes.
This sounds very promising vs electrical techniques.

“Recording deep neural activity via ultrasound can’t be done through the skull, but it can be done by removing a piece of skull and laying the device on the surface of the brain.”
I don't know much about how their stimulation is supposed to work, but I do know quite a lot about ultrasonic imaging and I can tell you this is not going to get you the neural interface that people really want. It's going to get you slightly better "think really hard and the drone flies!" toys.
> For stimulation, focused ultrasound waves can flexibly target specific regions throughout the brain from outside the skull.
