SUMMARY
UCLA researchers in the Department of Electrical Engineering have developed the first modulation system that allows simultaneous wireless power and data transmission through a single pair of inductive coils.
BACKGROUND
Next-generation Brain-Machine Interface senses neural data and stimulates the brain when needed, which requires simultaneous external power reception and outbound data transmission. The simultaneity or power and data is currently either not supported or achieved with sacrifices of device performance. Simultaneous power and data transmission may require high power consumption, limited transmission distance, or two sets of coils. There exists a need for a modulation system that allows simultaneous near-field wireless power and data transmission through a single pair of inductive coils.
INNOVATION
UCLA researchers in the Department of Electrical Engineering have developed the first modulation system that allows simultaneous wireless power and data transmission through a single pair of inductive coils. The system features Load Induced Frequency Shift Keying. The system allows for high-efficient power delivery over the entire regulating range, and high-rate (> Mbps) low-power (< mW) data communication.
