New wristband front-end integrates IMU and radar for gesture sensing

Researchers have developed a novel wristband front-end system for gesture sensing and motor symptom monitoring. This system integrates a micro-electro-mechanical-systems (MEMS) inertial measurement unit (IMU) with a 60 GHz frequency-modulated continuous-wave (FMCW) radar. The design features a single on-chip residual generator that handles classifier wake-up gating, radar versus IMU routing, and Kalman filter measurement reweighting, all within a coin-cell power budget.
