“…Magnetoelectric composites with large nonzero α E in the absence of a DC magnetic field, namely with a "self-biased ME effect," have been developed in various configurations using different strategies. 28 These self-biased ME composites are discussed in the article by Chu et al in this issue, 29 and their use for energy harvesting is illustrated. Further, using these ME composites, dual-mode energy harvesting can be accomplished, where both magnetic field and vibration can be simultaneously converted into electricity.…”

“…35 Particle/ granule spray deposition techniques such as aerosol deposition (AD) and granule spray in vacuum (GSV) are being investigated to synthesize the mesoscale structures with desired microstructure in a rapid manner. The AD/GSV deposition technique is briefly mentioned in the article by Chu et al 29 The articles by Roundy and Trolier-McKinstry and Torah et al 34,35 both address the energy-harvester requirements for the human body in the form of smart fabrics and textiles and also as wearables. There are several constraints in implementing flexible harvesters using films and fibers, which need to conform to curved surfaces, stretch, and be comfortable to the user.…”

sensor consisting of a ferromagnetic material surrounded by two coils, one of which is a drive and the other one is a sensing coil, is another widely used magnetic field sensor. The major advantage of the fluxgate sensor over search coils is its ability to precisely measure the weak direct current (DC) magnetic field. However, a fluxgate sensor typically consumes much more power than a search-coil sensor does; also, its sizes are normally big, limiting its applications as a magnetic sensor array for magnetic positioning and imaging. Superconducting quantum interference device is designed based on the Josephson effect, exhibiting the highest sensitivity. However, the need for a liquid-helium coolant for a superconductor magnetometers makes the complete instrument rather bulky and costly. Hall effect sensor, also viewed as a widely used and low-cost sensor, is unfortunately unable to detect a magnetic field weaker than 100 nT.Meanwhile, there are various techniques for metal detecting and metal imaging. Electromagnetic wave-based imaging technologies, such as millimeter waves imaging [3,11] and terahertz waves imaging, [2][3][4] typically employ the difference of transmissivity and reflectivity among different materials. However, this very expensive millimeter wave or terahertz wave technology cannot easily distinguish magnetic objects from nonmagnetic ones. In the case of magnetic imaging for medical application, magnetic induction tomography (MIT), magnetic particle imaging (MPI), and nuclear magnetic resonance (NMR) are typically used. [12,13] MIT technology applies the magnetic field to detect the existence of the object that is going to image. [14,15] The detection principle of the MIT system is based on the giant magneto resistance effect, which shows a high spatial resolution but a very small magnetic detection range too. For MPI and NMR technologies, a good resolution could be obtained; however, a high magnetic intensity is normally assisted. [13] In addition, the superhigh cost and the relatively big size limit the civil applications of MPI and NMR technologies. In the field of metal detection or security checking, X-ray or terahertz waves imaging technologies are normally utilized. But the problem is the body damage of the X-ray passing through a person or the privacy protection issue.Magnetoelectric (ME) effect is defined as the polarization induced by a magnetic field (H) or the magnetization induced by an electric field (E). ME sensors, which consist of ferromagnetic/ferroelectric composite materials Although various magnetic sensors have been developed, tiny magnetic object detection is still a challenging issue in some cases, such as capsule position detection, endoscope navigation, and the detection of magnetic devices hidden in/on the human body. In this paper, a magnetic detecting and sketching system utilizing a 1D magnetic sensor array with 56 magnetoelectric (ME) sensing units is proposed. The ME sensors used in this system are based on a (1-1) connectivity Metglas/piezofiber composite operatin...

Piezoelectric Energy Harvesting Design Principles for Materials and Structures: Material Figure‐of‐Merit and Self‐Resonance Tuning

Piezoelectric energy harvesters (PEHs) aim to generate sufficient power to operate targeting device from the limited ambient energy. PEH includes mechanical-to-mechanical, mechanical-to-electrical, and electrical-to-electrical energy conversions, which are related to PEH structures, materials, and circuits, respectively; these should be efficient for increasing the total power. This critical review focuses on PEH structures and materials associated with the two major energy conversions to improve PEH performance. First, the resonance tuning mechanisms for PEH structures maintaining continuous resonance, regardless of a change in the vibration frequency, are presented. Based on the manual tuning technique, the electrically-and mechanicallydriven self-resonance tuning (SRT) techniques are introduced in detail. The representative SRT harvesters are summarized in terms of tunability, power consumption, and net power. Second, the figure-of-merits of the piezoelectric materials for output power are summarized based on the operating conditions, and optimal piezoelectric materials are suggested. Piezoelectric materials with large k ij , d ij , and g ij values are suitable for most PEHs, whereas those with large k ij and Q m values should be used for on-resonance conditions, wherein the mechanical energy is directly supplied to the piezoelectric material. This comprehensive review provides insights for designing efficient structures and selection of proper piezoelectric materials for PEHs.
