Are brain waves the next unlock for physical AI?

TechCrunch AI Tim Fernholz

Encord, a data tooling company, is experimenting with brain wave sensors and muscle electrical signals to improve physical training data for humanoid robots, working with German startup Zander Labs. The company estimates that densely annotated physical training data is worth 100 times as much as basic video data but costs 20 times more to produce. The scarcity and high cost of real-world manipulation data has become a significant bottleneck for robotics companies developing physical AI models, creating a new business around manufacturing training data that doesn't exist at scale.

Why it matters

Forget YouTube videos—frontier physical AI models need multiple camera angles, dense annotation, and soon, brain wave readings.
