Hydrogels are cross-linked polymer networks that absorb liquid in a reversible swelling process. Owing to their versatility, biocompatibility, and hiMagnetoelectric (ME) composites offer an alternative route for electromagnetic coupling by relying on electro- and magneto-mechanical coupling materials, namely piezoelectric and magnetostrictive. Bending mode operation of ME devices provides an exceptionally low spatial size considering the frequencies involved, with applications in miniature antennae; this makes ME devices and bending mode operation in particular, very attractive.
Most reports dealing with bending mode ME discuss only the first mode. Herein we present the fabrication, operation, characterization and analysis of ME bending modes operation. This includes a model offering rigorous, analytical, expressions for experimentally observed outcomes in the fundamental as well as higher modes.
In this talk I will discuss the ME device design and fabrication process, including the effects of the adhesive layer on its performance; the measurement setup and procedure, and advanced operation modes and their analysis. Finally, the device’s functionality as an antenna will be discussed by evaluating its performance under varying conditions, including different distances, media, and transmitter types. These findings expand the design and application toolbox of ME composite technology, offering new insights into their potential for communication and energy transfer.
