A Smart Contact Lens Controller IC Supporting Dual-Mode Telemetry With Wireless-Powered Backscattering LSK and EM-Radiated RF Transmission Using a Single-Loop Antenna

This article presents a controller IC for smart contact lens (SCL). For wireless telemetry, we propose a transmitter supporting dual-mode operations with a single external loop antenna. In the wireless-powered backscattering load-shift keying (LSK) mode, the transmitter is configured to use the ante...
