UC Berkeley Team Proposes DustNet, a Wireless Network of Ultrasonic Neural Implants

Summary Engineers in the Muller Lab at the University of California, Berkeley have described DustNet, a wireless network of miniaturized ultrasonic implants that acquire and transmit neural signals without wires, in a paper in IEEE Transactions on Biomedical Circuits and Systems. The lab announced the work on its website on August 27, 2026. DustNet follows the lab's earlier MRDust ultrasonic neural interface.

Why it matters The interesting part is the topology, not the sensor: spreading recording across many untethered ultrasonic motes attacks the wiring-and-connector bottleneck in chronic implants rather than the decoding problem most BCI work chases. Whether the approach scales in bandwidth and channel count is what to watch next.

BCIwiki (bciwiki.com) — Researchers at Muller Lab, University of California, Berkeley, published a paper in IEEE Transactions on Biomedical Circuits and Systems describing DustNet, a wireless network of ultrasonic neural implants. The paper was announced on the lab’s website on August 27, 2026, with authors J. Pinkenburg, C. Lee, M. M. Ghanbari, C. Yalcin, M. Montalban, and R. Muller.

DustNet consists of multiple miniaturized ultrasonic implants that wirelessly acquire and transmit neural signals. The design aims to reduce physical connections of implants, potentially improving long-term stability. The paper is published in IEEE Transactions on Biomedical Circuits and Systems with DOI 10.1109/tbcas.2026.3705632.
