Electrochemical impedance spectroscopy (EIS) is a powerful analytical technique with critical applications in medical diagnostics, environmental monitoring, and materials science. However, its widespread adoption as a point-of-need tool has been hindered by a fundamental trade-off: high-performance instruments are typically large and expensive, whereas low-cost, portable alternatives often compromise on measurement accuracy and bandwidth. This thesis addresses this challenge by presenting a holistic approach to the design, implementation, and validation of a low-cost, high-performance impedance spectroscopy system designed to make this powerful technique accessible for ubiquitous diagnostics. This study fills a critical gap between high-end academic proofs-of-concept and limited-performance commercial solutions by co-designing a high-fidelity analog front-end, an efficient digital backend, and robust signal processing algorithms, all of which are designed to bridge the cost-performance divide.
