Abstract (EN): Growing environmental concerns and the demand for sustainable resource use have raised questions about the conventional use of lithium -ion batteries. In this context, solid-state sodium -based batteries are considered promising energy storage devices due to their excellent performance, cost-effectiveness, and eco-friendly composition. Despite their unquestionable storage capacity, this new battery type may possess additional functionalities that have not been thoroughly explored in the existing literature. In this study, the application of a novel battery developed by a research group at the University of Porto as a strain -sensing device under vibration loads is demonstrated. This battery is an all -solid-state sodium -ion -based ferroelectric battery, and it is expected to exhibit piezoelectric behaviour. With the goal of potential future applications in self -powered Structural Health Monitoring (SHM) systems, the experimental setup replicates conditions similar to those encountered in damage monitoring of composite structures. The solid-state battery is attached to an aluminium beam, which is clamped to an electrodynamic shaker. The beam -battery system is then subjected to constant -frequency excitation, and the battery's electric potential output is analysed in both time and frequency domains. The filtering of the acquired signal from the battery significantly reduced both the interference and harmonic distortion. The experimental results for the base excitation of 25Hz showed a dominance of the unfiltered 60Hz interference of +14 dB in relation to the unfiltered vibrational signal, while in the filtered situation the amplitude of the vibrational signal was +33 dB above the interference. The same tendency is observed under different frequency excitations. The results indicate that the battery generates a potential difference at the same frequency as that imposed by the shaker. However, its low sensitivity and susceptibility to electromagnetic noise from the electric grid limits the maximum frequency it can effectively monitor. Based on the positive results obtained in the present study, the authors believe that such a device opens up new possibilities for various applications of solid-state batteries, combining their energy storage capabilities with smart sensing functionalities.
