We have AE at home

The acoustoelectric effect

We have AE at home • acoustoelectric • functional ultrasound We have AE at home By: Ethan Childerhose , Kevin Chung, Andy Kong , Brian Machado , Marley Xiong The acoustoelectric effect (AE) allows us to precisely target tiny areas—as small as a millimeter—and use ultrasound to single out the electric field of a region. Our goal is to use it to make brain-computer interfaces with 27,000x more channels than EEG. We built a setup at home and replicated the AE effect. Our system is sensitive enough to measure acoustoelectric signals down to 250 nV with SNR > 1, despite no shielding or noise cancel
