Abstract State-of-the-art compact antennas rely on electromagnetic wave resonance, which leads to antenna sizes that are comparable the wavelength. As a result, typically have size greater than one-tenth of wavelength, and further miniaturization has been an open challenge for decades. Here we report acoustically actuated nanomechanical magnetoelectric (ME) with suspended ferromagnetic/piezoelectric thin-film heterostructure. These ME receive transmit waves through effect at their acoustic...
A novel very low frequency (VLF) communication system using one pair of magnetoelectric (ME) antennas has been proposed. The ME are strain-mediated acoustic resonators operating at their electromechanical resonance in the VLF band. measured near-field radiation pattern reveals equivalent to dipole antennas. magnetic field radiated by transmitter predicted along with distance ranging from 1 mm 100 km. distribution coincided well prediction, and maximum 120 m achieved. With 80 V driving...
An equation of state for carbon dioxide is developed here that yields high accuracy in P-V-T calculations over wide ranges temperatures (216-423 K) and pressures (to 310.3 MPa). It particularly accurate around the critical region due to use "nonanalytical" terms model isotherm. Thus it suited applications supercritical states. The density calculation reliable within 0.1-0.2 % outside region, 1% near point. has also been tested vapor pressure enthalpy (with deviations less than 0.06 %, 2-5...
A highly sensitive flexible magnetic sensor based on the anisotropic magnetoresistance effect is fabricated. limit of detection 150 nT observed and excellent deformation stability achieved after wrapping sensor, with bending radii down to 5 mm. The AMR used read a pattern thickness 10 μm that formed by ferrite inks. As service our authors readers, this journal provides supporting information supplied authors. Such materials are peer reviewed may be re-organized for online delivery, but not...
We report a highly sensitive NEMS DC/low frequency magnetic field sensor consisting of an AlN/FeGaB resonator, with ΔE effect-based sensing principle. Unlike previously reported detection schemes, such as observing induced magnetoelectric voltage, or monitoring impedance, we designed system to directly measure the reflected output voltage from function field. The resonator shows resonance shift 3.19 MHz (1.44%), which leads high DC sensitivity 2.8 Hz/nT and limit 800pT in unshielded, room...
Layered magnetic/piezoelectric heterostructures have drawn a great amount of interest for their potential use in ultra-sensitive magnetoelectric (ME) sensors, ME antennas, voltage tunable inductors, magnetic resonators, etc. It is critically important to characterize the saturation magnetostriction, piezomagnetic coefficient, ΔE effect, and magnetomechanical coupling factor thin films, which determine performance these devices. In this work, sensitive system has been developed measure...
Different degrees of roasting result in differences the quality and flavor large-leaf yellow tea. The current sensory evaluation chemical detection methods cannot meet requirement online differentiation LYT degree, so an accurate comprehensive assessment method needs to be developed urgently. First, two aroma sensing technologies were compared. Two variable screening three recognition algorithms employed build discriminant models. results showed that discrimination rate colorimetric sensor...
Measurements of the heat capacities alkanolamines monoethanolamine, diethanolamine, diglycolamine, di-2-propanolamine, triethanolamine, N-methyldiethanolamine, 2-amino-2-methyl-l-propanol, and 2-piperidineethanol were performed from 30 to 80 °C with a differential scanning calorimeter (DSC).
