Alternating strain response of fibre Bragg grating sensors embedded into carbon fibre composites for wind blade health monitoring

Incorporation of fiber Bragg grating sensors in additive manufactured Acrylonitrile butadiene styrene for strain monitoring during fatigue loading

“…FBGs are susceptible to breaking when exposed to certain environments and cannot always be embedded into structures due to manufacturing complexity and cost. For these reasons Zhu et al investigated the use of FBGs encapsulated into CFRP packaging for SHM in composite wind turbine blades [14]. This concept was first validated by viewing the strain transfer efficiency of the packaged sensors compared to theoretical values.…”

“…Many other applications of FBGs exist such as composite curing [14], temperature sensing [31]- [37], and biomedical implants [38] to name a few. In the biomedical field the idea of using FBGs to track human motion through wearable technologies could also be an area to explore [39][61].…”
