摘要： A torque sensor including a shaft that receives an applied torque is disclosed. The shaft includes a magnetoelastic region that generates a non-negligible magnetic field responsive to the applied torque and null regions that generate a negligible magnetic field. The torque sensor includes null region sensors that generate a null region magnetic field measure corresponding to an ambient magnetic field. The torque sensor includes a magnetoelastic region sensor that generates a magnetoelastic region magnetic field measure corresponding to the ambient magnetic field and the non-negligible magnetic field. The torque sensor includes a controller that determines whether a null region sensor has entered an intense ambient magnetic field condition and whether a magnetoelastic region sensor has entered a magnetoelastic region sensor saturation condition. The controller also calculates a magnitude of the applied torque based on the null region magnetic field measures and the magnetoelastic region magnetic field measure.

摘要： Disclosed in the present invention is a dual-rotor microfluidic energy capturing and power generating device based on a piezoelectric effect. An inner ring of blades and an outer ring of blades are coaxially and movably sleeved, and rotate relatively. Sheet-like magnetic piezoelectric components and steel magnets are provided in an annular gap between the inner ring of blades and the outer ring of blades. Magnetic piezoelectric components are connected to an inner peripheral surface of the outer ring of blades, the magnetic piezoelectric components are magnetically repulsive to the steel magnets, and the outer sides of the magnetic piezoelectric components are axially arranged. The inner ring of blades and the outer ring of blades rotate relatively to drive the magnetic piezoelectric components and the steel magnets to rotate relatively, and further drive the magnetic piezoelectric components to oscillate to generate mechanical energy which is then converted into electric energy.

摘要： A power generation element includes a magnetostrictive plate, a coil enclosing at least a part of the magnetostrictive plate, a magnetic field generation portion that generates a magnetic field, a yoke including a ferromagnetic body, and a non-magnetic body. The magnetostrictive plate contains a magnetostrictive material and has one fixed end. The power generation element generates power when force is applied to the magnetostrictive plate. The yoke spans from one towards another partial area of the magnetostrictive plate. The one partial area of the magnetostrictive plate, the non-magnetic body, and one end of the yoke at the one partial area of the magnetostrictive plate are disposed in this order. Another end of the yoke faces the other partial area through a gap. The one partial area is on one surface of the magnetostrictive plate and the magnetic field generation portion is provided on another surface of the magnetostrictive plate.

摘要： A method of manufacturing an ambient energy converter that includes a supporting substrate of a first conductor material as a first electrode, a layer of ferroelectric material, and a layer of a second conductor material as a second electrode. The two conductor materials have different concentrations of free electrons. The ferroelectric material includes one or more ferroelectric semiconductors. The method includes providing a plate of the conductor material for the first electrode as a supporting substrate, subjecting the carrier substrate to a surface treatment, depositing the layer of ferroelectric material (BTO layer) on a front side of the carrier substrate, masking the edges of the BTO layer on the front side of the carrier substrate while leaving at least one portion located within the edges of the BTO layer free, and applying the conductor material intended for the second electrode to the area kept free of masking.
