In this context, wireless transmission at THz frequencies represents a particularly attractive and flexible solution. Researchers have now developed a novel concept for low-cost terahertz receivers.

But, so far, when researchers have tried to create wireless brain-computer interfaces to do this, it took so much power to transmit the data that the implants generated too much heat to be safe for the patient. A new study suggests how to solve his problem -- and thus cut the wires.

Results are sent to a computer over Bluetooth, and any changes notify the user wirelessly. Mon, 03 Aug 2020 10:52:47 EDT //www.koonmotors.com/releases/2020/08/200803105247.htm
