Latest Patents

Daichi Chiba's latest patents include groundbreaking inventions related to stress sensors. One of his notable patents describes a stress sensor that consists of a stress detection layer comprising a laminated structure made up of ferromagnetic and non-magnetic layers. The unique composition includes a fixed magnetization direction for one layer due to the exchange bias from an antiferromagnetic layer containing manganese. This allows the sensor to detect stress through changes in electrical resistance, which depends on the relative angle between the magnetization directions of the ferromagnetic layers.

In another patent, Chiba presents a different approach to measuring stress. This sensor includes a laminated stress detection layer with two magnetic layers that have different magnetoelastic coupling constants. The detection mechanism is also based on the alteration of electrical resistance, dependent on the angle of magnetization between the two magnetic layers in response to externally applied stress.
