Reducing the Power Consumption of an IMU-Based Gait Measurement System

COVID-19 is shifting the adoption of wearable monitoring and telemedicine (WearTel) in the delivery of healthcare: opinion piece

“…IMUs usually contain a tri-axial accelerometer to measure linear acceleration in the forward (anteroposterior), sideways (mediolateral) and vertical axes, giving 3 degrees of freedom (DoF) in measurements. However, notwithstanding technological advancement, any such alteration to an IMU to increase measurement accuracy will substantially increase power consumption (19). As such, a compromise must be made to device accuracy to ensure longevity beyond a few hours, which is necessary for remote healthcare.…”
