TL;DR: An electric pulse generator utilizing a Matteuci effect is described in this article, where an alternating magnetic field is applied to distorted magnetic substances by a permanent magnet rotor, a polarizedly magnetized running sheet or an electric coil.
Abstract: An electric pulse generator utilizing a Matteuci effect. An alternating magnetic field is applied to distorted magnetic substances by a permanent magnet rotor, a polarizedly magnetized running sheet or an electric coil. The amorphous magnetic substances generate sharp pulse voltages between its ends, at the specific phase of the alternating magnetic field.

TL;DR: In this paper, the authors measured the stress applied to a target material by inducing a primary current in either the target material or a sensor material incorporated therein, measuring a secondary current that is subsequently induced in a sensing transformer 14; and calculating the applied stress based on the measured secondary current.
Abstract: Measuring the stress applied to a target material by inducing a primary current in either the target material or a sensor material 18 incorporated therein; measuring a secondary current that is subsequently induced in a sensing transformer 14; and calculating the applied stress based on the measured secondary current. The primary current may be induced by applying a voltage to an inducing transformer, e.g. a hinged (24, Fig.2) toroidal transformer 12 through which the target material passes. The sensor material may be an elongate 1mm-diameter shape memory alloy (e.g. Nitinol) wire embedded in a moving target rope, cable, wire or belt (52, Fig.5). The calculation may be based on known linear or non-linear relationships between electrical resistance and stress exhibited by the materials. The calculation may rely on baseline calculation made when the target material is unstressed and further calculation made when it is under stress.

TL;DR: The load measurement in a linear ferromagnetic element (1) involves passing an alternating current through the element to measure its ohmic resistance via contacts (5,6), and determining the load on the basis of the measured resistance values, using a relationship between the load data against resistance.
Abstract: The load measurement in a linear ferromagnetic element (1) involves passing an alternating current through the element to measure its ohmic resistance via contacts (5,6), and determining the load on the basis of the measured resistance values, using a relationship between the load data against resistance. The ferromagnetic element is made of an amorphous alloy based on iron. The frequency of the alternating current is at least 300 kHz. A flat sensor may be constructed of several parallel elements.
