摘要： The present invention provides a deformation detection sensor which combines a magnetic resin dispersing a magnetic filler in a resin with a magnetic sensor, of which stability of detection property is highly enhanced. The present invention thus provides a deformation detection sensor which comprises: a magnetic resin-containing polymer foam which comprises a magnetic resin, in which a magnetic filler is contained, and a polymer foam in which the magnetic resin is included, and a magnetic sensor that detects a magnetic change caused by a deformation of the magnetic resin-containing polymer foam, wherein the magnetic resin has a convex portion on either a surface facing the magnetic sensor or a surface facing opposite to the magnetic sensor, and its production method.

摘要： A force or pressure sensing device comprises one or more magnets resiliently held spaced from one or more magnetic sensors such that pressure on the device displaces the magnets relative to the magnetic field sensors. The device may be incorporated into an insole of a shoe, or integrated into a shoe, or integrated into a seat, cushion, mattress or saddle. The device includes one or more magnetic focussing elements on the opposite side of the magnetic field sensor from the magnets to focus and condition the magnetic field passing through the sensor. The magnetic focussing elements may be permanent magnets or magnetic materials having a high magnetic permeability such as mu-metals. Additional magnetic focussing elements may be placed adjacent to the magnets. Plural magnetic field sensors can be arranged in a symmetrical arrangement in a plane below the one or more magnets so that shear forces applied to the device causes lateral relative displacement of the magnet and magnetic field sensors changing the magnetic field sensed by the magnetic field sensors. The device can also include a motion detector such as an accelerometer which may be integral with the magnetic field sensor.

摘要： A load sensor unit is provided which is less likely to suffer from hysteresis errors. The magnetic load sensor unit includes a flange member, a support member supporting the flange member from the axially rearward side, a magnetic target fixed to the flange member, a magnetic sensor fixed to the support member. The magnitude of the load is detected based on the magnetic flux detected by the magnetic sensor. A load acting surface of the flange member to which the load is applied is formed at a position offset axially rearwardly relative to an axially forward surface of the flange member.

摘要： In order to improve a support unit for motor vehicles comprising a supporting structure mounted on a rear end portion of the motor vehicle a sensor unit is provided for detecting forces acting on the supporting structure and elastically deforming the same. The sensor unit is provided with a sensor base, comprising two fixation regions which are spaced apart and can be fixed to mounting regions of an elastically deformable supporting structure portion. A transformation region disposed between the fixation regions mechanically converts the movements of the mounting regions, and thus also of the fixation regions relative to one another. Movements are generated by the elastic deformation of the supporting structure portion, into a movement of measuring points of the transformation region relative to one another. The movement of the measuring points can be detected by the sensor unit.
