The Pig Paradigm: How Ultrasound 3D Printing is Breaking the Brain-Computer Barrier

Researchers in Shenzhen have pioneered a technique using ultrasound to 3D print electrodes inside a pig's scalp, allowing for high-fidelity brainwave capture without invasive surgery. This approach leverages the cost-effectiveness and biological similarities of pigs to humans, potentially disrupting the billion-dollar EEG market.
