An Energy conversion model for cantilevered piezoelectric vibration energy harvesters using only measurable parameters
TL;DR: In this paper, an energy conversion model of a cantilevered PEH that requires only geometric data and modal parameters that can be directly measured using a standard vibration test is proposed, which facilitates calculation of the maximum output power and enables visualization of the harvestable energy from the target vibrating structure.
An experimental method to design piezoelectric energy harvesting skin using operating deflection shapes and its application for self-powered operation of a wireless sensor network
TL;DR: In this article, a more practical way of designing the piezoelectric energy harvesting skin was proposed, which facilitates the application of the proposed idea to any practical engineering facilities with vi...

Non-contact modal testing by the electromagnetic acoustic principle: Applications to bending and torsional vibrations of metallic pipes
TL;DR: In this article, a non-contact vibration modal testing for bending and torsional motions of cylindrical bodies such as pipes is investigated. But the main characteristic of the proposed transducer is non-touch vibration generation in a test specimen without any mechanical movement of the actuating unit.
