State-Space Model Of An Electro-Mechanical-Acoustic Contactless Energy Transfer System Based On Multiphysics Networks


Contactless energy transfer systems are mainly divided into acoustic, inductive, capacitive and optical, in which main applications are related to biomedical, wireless chargers and sensors in metal enclosures. When solids are used as transfer media, ultrasound transducers based on piezoelectricity can be used for through-wall power transfer, which can be named as electro-mechanical-acoustic con... » read more
