Resumo

This study presents an acoustic emission (AE) monitoring strategy based on MEMS (Micro- Electro-Mechanical Systems) sensors applied to 3D-printed structures. AE data were analyzed using the b-value method to track damage development and Natural Time (NT) analysis to identify the onset of critical conditions. A comparison with a commercial piezoelectric sensor revealed similar performance, with both sensors detecting a reduction in the b-value preceding failure. MEMS sensors demonstrated an enhanced capacity to capture high-frequency signals. These results underline the potential of MEMS sensors as cost-effective tools for structural health monitoring in additive manufacturing contexts.
