摘要: A sensing device for measuring electric current and electric power including a plurality of magneto-electric transducers for detecting a magnetic field about a conductor carrying the electric current. The magneto-electric transducers can include Barber-Pole type elements, each element being positioned on a substrate at approximately the same distance from the central point of a substrate.

摘要: An acceleration sensor including a cantilever beam having a free end to which a permanent magnet is attached. A pair of magnetic sensors, each comprising a barber-pole type magnetoresistive sensing element, is arranged in symmetrically spaced and opposed relationship and in a common plane extending parallel to the magnetic flux of the permanent magnet with respect to respective, opposite sides of the magnet. The cantilever is bent and the magnet is moved accordingly in response to an acceleration force, which is detected as outputs from the magnetoresistive sensing elements.

摘要: A magnetic field sensor for an acceleration sensor including a cantilever beam having a free end to which a permanent magnet is attached. A pair of the magnetic sensors, each consisting of a barber-pole type magnetoresistive sensing element, are arranged opposite to and symmetrically. The cantilever is bent and the magnet is moved according to an acceleration, which is detected as outputs from the magnetoresistive sensing elements.
