The characteristics of Lamb waves, which are multimodal and dispersive, provide both challenges and opportunities for structural health monitoring (SHM). Methods for nondestructive testing with Lamb ...

We established and tested an unconstrained sleep apnea monitoring method using a polyvinylidene (PVDF) film-based sensor for continuous and accurate monitoring of apneic events occurred during sleep.

Potassium-ion batteries are an emerging post-lithium technology that are considered ecologically and economically benign in terms of raw materials’ abundance and cost. Conventional cell configurations ...

In this work, a poly (vinylidene-fluoride- co -hexafluoropropylene) (PVDF-HFP)/poly (methyl methacrylate) (PMMA) matrix GPE, containing bis (trifluoromethane)sulfonimide lithium salt (LiTFSI) and ...
