Development of a Portable Impedance Tomography System for Real-Time Bioelectrical Analysis

Electrical impedance analysis offers a non-invasive approach to assess the density and composition of various materials. This research presents the development of a portable bio-impedance tomography system utilizing the AD5933 integrated circuit, designed for measuring complex impedance. By employing multiple electrode pairs, the system creates twodimensional (2D) tomographic images, interfacing seamlessly with the human body through an analog front end and Bluetooth Low Energy (BLE) for real-time wireless data transmission. The platform, designed to be mobile and user-friendly, enables advanced bio-impedance measurements, laying a foundation for future applications in healthcare and wearable technology.
