Magneto-Electric Laminate Composite Type Magnetic Field and Electric Current Sensors Operated in the Longitudonal-Longitudonal (L-L) Mode, and Longitudonal-Tranverse (L-T) Mode
This is a new device design of a magneto-electric laminate composite for magnetic field and electric current sensing. This sensor gives high dynamic range. It gives magneto-electric coefficients 10-100x greater than any previous design.

Near-ideal (colossal) Magnetoelectricity in High-Permeability Magnetostrictive/Piezo/Fiber Laminates
Manetoelectricity is the interaction between the polarization and manetization subsystems of a solid. Giant mangeto-electric (ME) effects are known in laminate composites of magnetostrictive and piezoelectric layers, which are orders of magnitude higher than those of single phase systems. Theoretically, the longitudinally-magnetized longitudinally...

New Magneto-Electric Transformer with Higher Voltage Gain
-Conventional transformers are electromagnetic types, which use a ferromagnetic body and one pair of primary and secondary coils wrapped around it. To obtain a high voltage step-up ratio, a high number of turns-ratio is required. For example, if a transformer with a voltage gain of 100x is needed , a 100 turn primary coils and a 10,000 turns seco...
