Wireless Power Transfer Systems

This paper reviews the current status and implementation of battery chargers, charging power levels, and infrastructure for plug-in electric vehicles and hybrids. Charger systems are categorized into off-board and on-board types with unidirectional or bidirectional power flow. Unidirectional charging limits hardware r…

This paper presents an electromagnetic (EM) vibration-to-electrical power generator for wireless sensors, which can scavenge energy from low-frequency external vibrations. For most wireless applications, the ambient vibration is generally at very low frequencies (1-100 Hz), and traditional scavenging techniques cannot…

This paper reviews the current status and implementation of battery chargers, charging power levels and infrastructure for plug-in electric vehicles and hybrids. Battery performance depends both on types and design of the batteries, and on charger characteristics and charging infrastructure. Charger systems are catego…

We proposed and demonstrated metamaterial-based strain sensors that are highly sensitive to mechanical deformation. Their resonance frequency shift is correlated with the surface strain of our test material and the strain data are reported telemetrically. These metamaterial sensors are better than traditional radio-fr…

This paper presents a new vibration-based electromagnetic energy harvester using a mechanical frequency up-conversion method for harvesting energy from external low-frequency vibrations within a range of 1-10 Hz. The structure consists of a magnet placed on a diaphragm, a polystyrene cantilever carrying a pick-up coil…

This paper presents an electromagnetic (EM) vibration-to-electrical power generator which can efficiently scavenge energy from low-frequency external vibrations. The reported generator increases the conversion efficiency by up-converting the low-frequency environmental vibrations to a much higher frequency. Power is g…

This paper presents a microelectromechanical-system-based electromagnetic vibration-to-electrical power generator that can harvest energy from low-frequency external vibrations. The efficiency of vibration-based harvesters is proportional to excitation frequency, so the proposed generator is designed to convert low-fr…
