Non-contactSelf-poweringA novel magnetic force driven noncontact electromagnetic-triboelectric hybrid nanogenerator for scavenging biomechanical energy to sustainably power portable electrics is presented. Based on the effective conjunction of electromagnetic induction and triboelectrification, the hybrid nanogenerator...
Is contact force related to the electromagnetic force? Is the magnetic force stronger in the North Pole or South Pole? Does kinetic friction oppose motion? What is a force that opposes motion between two surfaces that are in contact? When does the magnetic force equal the centripetal force? Wh...
Magnetic Force Microscopy(MFM) is a noncontact scanning force technique that uses magnetostatic interactions between tip and sample to image magnetic domains. MFM is a derivative of atomic force microscopy and can be performed with many commercial AFM instruments. The magnetic structure of a wide var...
To enable sensitive static force measurements, low spring constant cantilevers are necessary. Generally, they work well for contact mode measurements or in pendulum geometry. However, they are not easily usable for dynamic mode measurements in conventional cantilever geometry since attractive contributions ...
Small cantilevers with a megahertz-order resonance frequency provide excellent sensitivity and speed in liquid-environment atomic force microscopy (AFM). However, stable and accurate oscillation control of a small cantilever requires the photothermal exc
On the other hand, intense electromotive force is generated by magnetic coupling in the double-tuned loop-type coil 71 to which the RF magnetic field is applied, and the cross diode 34 is turned on. The parallel resonant circuit 57 having the capacitor 26 and the inductor 16 resonates at ...
We have imaged vortices in superconducting thin films with a low-temperature magnetic force microscope that utilizes microfabricated piezoresistive cantilevers with built-in tips. The films of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} and Bi{sub 2}Sr{sub 2}Ca{sub 1}Cu{sub 2}O{sub ...
