Abstract: The method involves providing a sensor, a sending or receiving unit, and a measuring device or an actuator. A core element (2), arranged in a magnetic field by thermal excitation, is caused a cyclic change of the magnetic flow or the magnetic force through a coil (8). A measurable current or a voltage is induced or provided by the magnetic flow and/or change of magnetizing force in the coil. The core element is made of a lanthanide, particularly gadolinium. Independent claims are included for the following: (1) a thermo-magnetic generator for generating electricity; and (2) an electrical device, which has an electronic or electrical device.

Abstract: The method involves using cool air flow (1) or temperature difference in a device, a machine or a system for generating electrical energy using a thermoelectric converter. The generated electrical energy is supplied to a measuring and transmission unit in an engine (2) using an electrical generator that is coupled to a micro fan/micro blower (3), where the measuring and transmission unit consists of a sensor, an evaluation unit and a transmission device for transmitting measured values to an external receiving device. An independent claim is also included for an electrical energy generation device comprising a sensor.
