New Insights on Hydration Monitoring in Elderly Patients by Interdigitated Wearable Sensors

Sensors (Basel). 2025 Nov 20;25(22):7081. doi: 10.3390/s25227081. ABSTRACT The progressive aging of the population requires reliable, non-invasive, and real-time tools to monitor hydration, prevent dehydration-related complications, and promote active aging in elderly patients. Wearable sensors based on interdigitated electrodes (IDEs) and on Electrochemical Impedance Spectroscopy (EIS) represent a promising tool thanks to their miniaturization, sensitivity…
