Wireless Telemetry

Definition

Wireless telemetry is the technology that allows for the transmission of data over a distance without the use of wires or cables. In the context of neuroprosthetics, it is crucial for enabling real-time communication between invasive recording methods like microelectrodes and ECoG (electrocorticography) systems and external devices for data analysis or control. This technology enhances the feasibility and effectiveness of brain-machine interfaces by minimizing patient discomfort and movement restrictions during neural recordings.
