Use of Magnetomechanical Effect for Energy Harvesting and Data Transfer

Abstract

The presented paper describes a method where, with the use of a dedicated SMART Ultrasonic Resonant Power System (SURPS) developed by the authors, a power and data transfer between two devices can be performed at the same time. The proposed solution allows power to be supplied to the sensor, located in a hardly accessible place, with simultaneous data transfer in a half-duplex way (e.g., “question–response”). The power transmission mechanism is based on the excitation of a construction with a sinusoidal wave, with an actuator transforming this wave into useful, electrical power through a harvester device. Data transfer is achieved with the use of the F2F (Frequency Double Frequency) procedure, which is a kind of frequency modulation. To receive optimized parameters for each construction, an original software is developed, which allows the selection of the proper type of actuator, modulation, and frequency.

“…Mech et al [1] studied magnetomechanical harvesting and the related possibility of data transfer, investigating a novel hybrid solution focusing on rapid demagnetization [2]. Hadas et al [3] explored an electromagnetic harvester for railway applications, where energy is transferred from the vibration of the rails during train operations, thereby leading to applications that can encompass monitoring.…”
