*Equally Credited Authors (ECAs) 1 Abstract This paper presents a frame-rate-scalable duty-cycled electrical impedance tomography system to reduce average power consumption. A proposed multiple-input multiple-output current-balancing IA halves power consumption, area, and input parasitics. Digital matched filters with harmonic-canceling FIR filters significantly reduce settling time, improving system throughput. The system achieves 878.9fps at 662.0μW and 27.5fps at 43.8μW. Electrical impedance tomography (EIT) systems have been explored beyond their traditional imaging applications, such as lung ventilation monitoring [1–4], extending into humancomputer interface, including gesture recognition [5,6]. Despite its high potential, adapting the EIT system into portable and real-time interactive platforms remains challenging, primarily due to two critical bottlenecks: high power consumption and low frame rates (Fig.
