Wearable Electrochemical Biosensors for Advanced Healthcare Monitoring.

This research explores how to design, model, and process signals from wearable electrochemical biosensors that can monitor health continuously without breaking the skin. Wearable bio‑electronic devices could change personalized medicine by measuring biomarkers such as glucose, lactate, electrolytes, and cortisol in real time. They draw these signals from sweat, interstitial fluid, or saliva. The proposed work centers on building strong signal‑conditioning circuits, creating noise‑reduction algorithms, and developing calibration models. These tools aim to overcome motion‑induced artifacts, temperature changes, and sensor drift that occur in everyday use. Mathematical models and simulations of the electrode‑electrolyte interface are used to assess the sensitivity, selectivity, and stability of sensor arrays that measure several analytes

at once. The study also examines low‑power potentiostat designs and wireless data‑transfer protocols to keep power use low while preserving data quality. This resource gives M.Tech students a step‑by‑step guide to simulate, test, and improve electrochemical signal‑acquisition pipelines, laying a solid foundation for advanced biomedical instruments and wearable health monitors.
