Hybrid energy harvesting from wind and vibration

Just as one would go for regular check-ups, structural health monitoring is essential for any structure to determine its structural health. Such monitoring is crucial to ensure that the said structure is still structurally sound and is not at risk of collapsing. Sensors installed in strategic locati...
